An'Shaleria

Flying
Instant and sorcery spells you cast have replicate {x}{u/r}, where X is the number of +1/+1 counters on An'Shaleria. (When you cast those spells, copy it for each time you paid their replicate cost. You may choose new targets for the copies.)
Whenever you pay a spell's replicate cost, put a +1/+1 counter on An'Shaleria.
