Otterfolk Sparkflinger

Scorching—Whenever Otterfolk Sparkrunner
deals combat damage, it deals 1 damage to target opponent.
At the start of your post-combat main phase, you
may cast target instant or sorcery card with mana
value X or less from your graveyard, where X is
the total amount of non-combat damage dealt to
your opponents this turn. If that spell would be
put into your graveyard, exile it instead.
