The Art of Extinction

At the beginning of your upkeep, put a -1/-1
counter on each creature, then exile all creatures
with zero toughness. Then, exile all permanents
with the same name as that creature.
Players can't cast spells with the same name as
any card in exile.
"Extinction's wrath is unforgiving and apathetic. It
comes for all who oppose it, and even swifter for all
who don't." - A Simic Biomancer
