Aspiring Wizard

Ambitious (Whenever this creature becomes untapped, choose a creature on the battlefield. Until end of turn, this creature gains all activated abilities of this creature.)
Whenever Aspiring Wizard's Ambitious ability goes on the stack, you may choose target activated ability the creature that you chose with Aspiring Wizard's ability has. Aspiring Wizard gains that ability. (This effect lasts indefinitely.
Mana abilities can't be targeted.)
