When Tsk, Forgetful Cleric enters the battlefield,
exile the top 5 cards of your library face down.
Keep only the top card revealed. You may cast each
top card as if it had flash. When you cast a card,
leave it face up and put it at the bottom of the pile.
When each card that was exiled by Tsk is played,
Choose one card from the exiled pile. You may cast
a copy of that spell at any time.

Red and Black until end of turn.
