Joel, the Firehazard

Whenever you cast a noncreature spell, exile the top card of your library. You may cast it this turn. If it’s an instant or sorcery, it costs 1 less to cast. At the beginning of your end step, if you’ve cast three or more spells this turn, create a 3/1 red Construct token with trample and “Sacrifice this at end
of turn.”

“Wait, I've got an idea! Let's.. break it!”
