Alchemist and the Ogre

Greevil's Greed - Whenever a creature that was dealt damage this turn by Alchemist and the Ogre dies, put a gold counter on this creature. Then, create X Treasure tokens, where X is the
number of gold counters on Alchemist and the Ogre.

When Alchemist and the Ogre attacks, it gains
+X/+0 until end of turn, where X is the number of treasure tokens you control.
