Alex, Audacious Alchemist

At the beginning of your upkeep, create a
Clue token. Then, if you have 3 or more Clue
tokens on the battlefield under your control, exile
target creature from any graveyard and create a 2/2
blue Homunculus creature token. If no creatures
can be exiled this way, draw a card instead.

“He who dares to tread where wisdom fears to walk,
finds the alchemy of progress.”
— Lord Alexander Hull
