A couple of these cards requires that you have Toon World (or Toon Kingdom, which counts as Toon World) in play when you play them. One only requires that you have a Toon monster in play (which often means you’ll have Toon World or Toon Kingdom in play anyway). Each has an effect that is definitely useful.
If you control “Toon World”: Target 1 face-up monster your opponent controls; inflict damage to your opponent equal to the ATK of that face-up monster. You can only activate 1 “Shadow Toon” per turn.
This is a very powerful spell card! With some of the more powerful Xyz and Synchro monsters out there, this spell could finish off an opponent in one shot! While not good in every match-up, this is a nice card to have in your sideboard. Having three of these in your deck may be all you need to finish off certain decks.
If you control “Toon World”: Target 1 face-up monster your opponent controls; Special Summon 1 Toon monster from your hand or deck, whose Level is less or equal to the Level/Rank of that monster, ignoring its Summoning conditions.
There are quite a few awesome things about this card. Not only do you get to Special Summon a monster, but you can get that monster from either your hand or Deck! Also, that creature’s summoning conditions are completely ignored. But the best thing about this card is that it considers either Rank or Level. So you can target your opponent’s Xyz monster as well. It’s a pretty sweet way to pull out one of your best Toon monsters in response to one of your opponent’s big threats. In some Toon deck builds, this might even be worthy of the main deck! However, it is a bit situational, as it does depend on the Ranks and Levels of creatures that your opponents play.
Target 1 Toon monster you control; it can make a second attack during each Battle Phase this turn.
With Toon monsters in particular, an extra attack is a big deal. This is because pretty much any Toon monster out there can attack your opponent directly if they control no Toons and you have Toon World in play. Getting an extra attack out of your Red-Eyes Toon Dragon or Toon Dark Magician is particularly devastating. Is this card good enough to be playing in your main deck? Maybe.
What do you think of these three Toon cards? Are there other Toon cards that you think are worth playing?
