Mirel, Mistress of Miracles

Whenever you cast a card for its miracle cost, you get a experience counter.

At the beginning of your upkeep scry X where X is the amount of experience counters you have.

Spells you cast cost {x} less to cast where X is the number of Experience counters you have.

{x}: Scry X, then draw a card. Activate this ability only during an opponents turn and only once per turn.
