Amon, Multiversal Heir

Whenever a creature dies while this card is in the command zone, you get an experience counter.
Whenever you cast your first instant or sorcery spell each turn, if it's converted mana cost is less than or equal to the number of experience counters you have, exile it as it resolves.
When Amon, Multiversal Heir enters the battlefield you may cast any number of cards exiled by it.
