Evelyn, the Covetous
{2}{U/B}{B}{B/R}Legendary Creature — Vampire Rogue
Flash Whenever Evelyn or another Vampire you control enters, exile the top card of each player's library with a collection counter on it. Once each turn, you may play a card from exile with a collection counter on it if it was exiled by an ability you controlled, and you may spend mana as though it were mana of any color to cast it.
