Aghanim, Apex Mage

Creeps and creature tokens you control get +2/+2.
When Aghanim, Apex Mage enters, enter
the labyrinth.
At the beginning of your end step you may tap two untapped creatures you control. If you do, venture
into the dungeon.
Whenever you complete a dungeon, create a
colorless Crystal artifact token with "When this
artifact enters, exile target nonland permanent until
this artifact leaves the battlefield."
