While Konami created the captured the game of Duel Monsters more faithfully than Bandai did, there’s still a lot of inconsistencies between how cards were used in the show and manga, and how they appeared in real life. Most often, the case is that a card is severely watered-down, being thought of as too powerful, but today, most cards in the TCG far surpass these cards, even in their original form. This is a partial list of the some of the notable mistakes that were made in the transition. Some, however, actually improved when made into real life cards.
Graverobber – While it remains a useful card, its effect has been greatly changed from how it originally appeared. As Joey Wheeler used it, any card your opponent used (Magic/Trap/Monster) can now be used against them. In real life, it’s limited to only Magic cards. That may have been fine, but the cost of 2000 is pretty ridiculous. At this time in the series, Lifepoints were 2000, so this card would pretty much be an automatic suicide, if activated.
Mirror Wall – The actual effect was translated pretty well from how Mai Valentine used it against Yugi – then there’s the cost. As with Graverobber, the cost is an insane 2000 per turn. Although it was an extremely powerful card in its original appearance, it’s not powerful enough to warrant the inevitable damage it’ll do to your Lifepoints.
Copycat – This card is actually has some advantages over the original. Its original level was 5, which didn’t mean much in Duelist Kingdom, but in real life, it would have made him slightly harder to summon. Meanwhile, the effect was tweaked so that it only affected monsters instead of all cards your opponent played. The original also had 100 DEF, which would put it at a slight advantage to the original monster it copied.
Revival Jam – This was one of the cards that almost destroyed Yugi in the show. In real life, the effect was tamed down as much as possible, while still allowing it to come back as it had in the show. First of all, the effect was not immediately after its destruction, and second, the cost was an uneasy 1000. Not nearly as effective as its original counterpart.
The Seal of Orichalcos – The original UpperDeck card actually had an authentic effect (right down to the soul stealing), but the Konami version didn’t go that far. While watered down, it’s still legal, which is alright. Most notably, instead of a second row of monsters, it’s that only one monster can be attacked at a time.
Every Toon Monster – I don’t know where Konami got the inspiration to give the Toon Monsters the effects they had; the ‘direct attack’ feature was not used anywhere in the source material, in fact one direct attack from a Toon Summoned Skull or Blue-Eyes Toon Dragon could immediately win the duel with 2000 Lifepoints. The cost of 1000 Lifepoints to activate Toon World and 500 Lifepoint cost per attack is also something that would never have a place in the original arc. I don’t even know if the Toon monster archetype should have even existed; wasn’t it Toon World’s effect that all monsters on your side of the field become Toons? And a simple translation of Toons’ effects can be as easy as “cannot be destroyed by battle” or “cannot be declared as an attack target” instead of the direct attack effect. This change is especially big because it completely changes the way the deck is played.
Pumpking King of the Ghosts and Castle of Dark Illusions – This one’s a double feature, and may be the result of a mistake. Or at least that’s the only way I can rationalize Castle of Dark Illusions having Pumpking’s effect! The effects would have actually worked, had they been swapped (though Pumpking’s is still a bit strange; there’s no relation between the two cards). Can’t complain that Castle of Dark Illusions doesn’t have it’s original effect, as that would be hard to translate into real life.
Big Shield Gardna – Let’s be honest; if this monster had his real life effects, Yugi would be in a lot of trouble. In the show, it was a simple normal monster with extraordinary defense. But to make up for this in real life, it was given the awful cost of having it turned to ATK position after it’s been attacked, which pretty much means a direct attack against Big Shield Gardna’s 100 ATK. Meanwhile, he was given an additional effect of negating Magic cards that target it, which seems kind of pointless.
Labyrinth cards – In the anime and manga, the Labyrinth duel was its own playing style, with exclusive cards only used for this situation (Labyrinth Wall, Jirai Gumo, Magical Labyrinth, Wall Shadow). Such an instance made for an interesting duel, but one that was not practical in real life. As a result, these cards’ translations are often strange and mystifying (Wall Shadow was clearly a fusion between Labyrinth Wall and Shadow Ghoul), and are difficult to use in real life play. Labyrinth Wall is the only one to remain useful as a solid wall monster in real life.
Graceful Dice and Skull Dice – The original effects and real life effects are both related, and watered down in the same fashion. Originally, Graceful Dice and Skull Dice multiplied or divided its targets ATK by the dice result (Graceful Dice had a maximum ATK requirement of 500 ATK). This was changed to increasing the ATK and DEF by the result x 100. While Skull Dice would have been devastating in real life, Graceful Dice would have been a decent power-up to a weak monster. The real life effects were pretty mediocre, and easily replaceable with cards that could guarantee a higher result (Rush Recklessly and Mask of Weakness for example).
Granadora – Originally, if this card stayed face-up on the field in DEF position, the owner increased their Lifepoints by 1000. This is harder than it seems, due to the weak DEF of 700. Keep in mind, this same effect was seen in Spirit of the Breeze (with the exception of it being in ATK position). In real life, the card only increases the owner’s Lifepoints once it’s immediately summoned, and decreases it by a whopping 2000 once it’s destroyed, making players more cautious to use this card with its inevitable backfire.
Every Fusion Card That Was Originally Normal – There was really no reason for changing normal monsters from the original manga/anime into Fusion cards in real life; Konami must’ve been on a roll with printing Fusion cards at the time. There’s a lot of instances of this happening, although Flame Swordsman is probably the most notable example.
Mask of Brutality – This effect actually differed significantly between its manga adaption and anime adaption due to the real life card being made in between adaptions. The original effect was simply increasing a monster’s ATK by 700. This would have been fine, but the folks at Konami thought this just wasn’t enough, and increased it to 1000 points – while also decreasing the DEF by 1000, and having to pay 1000. An extremely unnecessary cost (especially in the realm of 4000 Lifepoints), especially when it’s bested in just about every single way by the costless Axe of Despair, which was released earlier, and features the additional perk of being sent back to your deck.
Call of the Haunted – Very rare and useful in the show and manga, and still useful in the real life game. But in the original, this card was a Magic card and immediately revived any [non-Zombie] monsters destroyed by battle as Zombies, who not only revive, but increase ATK each time they come back. While this effect may have been too powerful for real life, limiting it to one monster was acceptable, but could they have at least kept it a Magic Card?
Thousand Dragon – Konami didn’t really know how to go about making this card in real life, but as one of Joey’s most important cards, they went ahead and made it a Fusion monster with Time Wizard. They later made a more accurate summoning condition when they released Dark Sage (speaking of which, Dark Sage’s effect was severely watered down for his release).
The Egyptian Gods – The release of the Egyptian Gods were fairly accurate (except they got lazy with Ra’s effect and only had his ATK increase in multiples of 100), but there’s one fatal flaw; cards that don’t target can destroy them. This directly contradicts how they were used in the manga and show, specifically when Kaiba’s attack with Obelisk on the Rare Hunters shattered Mirror Force. In the real life game, Obelisk would have been destroyed. Lame.
Insect Armor with Laser Cannon – 700 points is a lot less than 1500 points, wouldn’t you say? Anyways, early in the game, the idea was that Insect cards were generally weak, but that has since changed.
Mystic Box – This effect was intentionally vague when used by Yugi, but if used in combination with your powerful monsters in real life, it will only backfire, and shift control of the monster to your opponent. Probably wouldn’t work to Yugi’s advantage.
Metal Reflect Slime – The real life card is more powerful than its use by Marik; the DEF of the summoned monster is ¾ of the ATK of an opponent’s monster that reduced the player’s Lifepoints by more than half. But Konami got lazy and simply transferred this card’s usage with Obelisk the Tormentor.
Riryoku – This card was decently powerful in the anime and manga, with the ability to halve your opponent’s Lifepoints and add them to a monster in your control. With 2000 Lifepoints, this wasn’t too bad, but with 8000 Lifepoints, this could spiral way out of control. The real life effect has a similarly powerful ability, which halves another monster’s ATK instead to add to the targeted monster’s ATK.
Magical Hats – Alright, this one gets excused because it’s effect in the show and manga required the use of holograms; something we don’t quite have yet. The real life solution of mixing the facedown monster with two Magic/Trap Hat Tokens created a similar guessing game for the opponent. But instead of the famous four hats, it was reduced to three, and the effect no longer lingers, making the real life card slightly less useful (in addition to draining two of your Magic/Trap cards).
Multiply – In the show and manga, this card was used most effectively when combined with Kuriboh, creating an unlimited supply of them. When used with other monsters with ATK <500, it simply splits them as the real life card does. Unfortunately, this card can only be used with Kuriboh in real life, and only uses your available monster card zones.
Living Arrow – Yugi uses this card to use his opponent’s spells. Meanwhile, the real life card destroys opponents Spell cards. For the amount of time it took to release this card, you’d think they’d get this right (in addition to changing the name and the artwork).
Parasite Paracide – With the real life card, you can now effectively use it against your opponent in the same way Weevil did, but without cheating! It has the additional effect of inflicting 1000 points of damage as well.
