Seto Kaiba The Prodigy

Persist, Decayed

When Seto enters, create a treasure and a clue.

Whenever you cast a spell using mana from a treasure, put a +1/+1 counter on Seto.

Whenever a creature you control with power 5 or greater dies, you may pay {u/r}{w}. If you do, search your library for a card named Blue Eyes White Dragon and put it into your hand.
