Aymar, Severin and Prize Sow for infinite-ish shenanigan's, establish combo, hit end turn and grab a drink while your opponent rages!
If you are not familiar with how this works, this combo creates a soft lock that will play the max amount of cards before ending the turn.
If you set up Sow, Aymar, Severin, then drop a power or whatever you have to do to kill a creature, it will start generating Piercing Griefs, which die to Aymar, which give you an influence from Sow, which gives you a Piercing Grief. As soon as the chain starts you get the option to click End Turn, which will end when it plays 40 or 50 cards.
This list is a WIP and not at all optimized.
EDIT: Also, yes there is a weird glitch where you end the turn with the remaining piercing griefs in play.
