I've seen a lot of recent hubbub over the fact that Burn is still heavily represented, and frankly yes, that's going to be the case, especially on MTGO leagues, because the deck is fast, but realistically, the deck's overall power level has seemed rather just fine since the bannings
Whenever you cast a noncreature spell, put a +1/+1 counter on Vivi Ornitier and it deals 1 damage to each opponent
Captain Hook Captain of the Jolly Roger does this only for an action card named Fire The Cannons

You [and its controller each] draw a card [and lose 2 life]
