Sadly, no Yujin support. You do get Beast-Type support, tho’!
RD/KP06-JP065 獣騙し Kemono Tamashi (Mere Beast’s Play/Kitty Stuff/Scaredy Cats)
Normal Trap Card
[Requirement] If you control a face-up monster (Beast-Type), you can activate when your opponent Normal or Special Summons a monster face-up.
[Effect] Choose 1 face-up monster your opponent controls, it loses 1000 ATK until the end of the turn. Then, choose 1 Normal Monster (Level 1/Beast-Type) in your Graveyard ad Special Summon it to your side of the field face-up.
Note: This is either a play on 子供騙し (Mere Child’s Play) or 猫騙し (Slapping Hands in front of an opponent’s face to stun them, a sumo move). Flip a coin, all these names should work.
