Krellius, Avian Trinket-Thief

Whenever an opponent draws a card, that player
may pay {1}. If the player doesn't, you create a Treasure token. (It's an artifact with "{t}, Sacrifice
this artifact: Add one mana of any color.")
Whenever a creature an opponent controls dies,
create a Treasure token.
"Jewels, gold, bright stuffs, anything valuable catches
my eyes."
