Eccentric Prodigy

Whenever you cast an instant or sorcery spell, choose one —
• Put a +1/+1 counter on each creature you control.
• Tap a target creature and put a stun counter on it.
(If a permanent with a stun counter would be come untapped, remove one from it instead.)
• Scry 2, then draw a card.
