Idel, Hero of the Dakra Isles

Each instant and sorcery spell you cast costs {1} less to cast for each creature it targets.
Whenever a creature you control becomes the
target of a spell, put a coral counter on Idel.
{t}: Remove X coral counters from Idel: Scry X.
Then, if X is 3 or greater, draw a card. Then, if
X is 7 or greater, return target instant or sorcery
card with mana value 3 or less from your
graveyard to your hand.
