Protector of the Unworthy

Flying
Whenever you cast a non-creature spell with
mana value 3 or less, it gains Thunderbound {2}{u/r} (When you cast this spell, you may pay its thunderbound cost. If you do, copy it for each creature
that dealt combat damage to another player this turn.)
"Who said there are no assurances in life? I assure
you this is going to hurt."
