Niv-Mizzet, Parun Good ol' Niv-Mizzet, Parun is here to kill foes, draw cards, and chew jalapeo-flavored bubblegum
And this doesn't have the modern templating of "return target creature an opponent controls" as you can bounce your own thing
This Glissa wants to deal combat damage to players for some incredible value
Of course, you can enchant your own creature and use the same threat of removal to discourage opponents from blocking and triggering the Rig
