Rathalkan Caravangate

Indestructible
When Rathalkan Caravangate enters the battlefield, if it isn't a token, create a token that's
a copy of it under an opponent's control.
At the beginning of your upkeep, draw a card
and create a colorless Treasure artifact token with
"Tap, Sacrifice this artifact: Add one mana of
any color to your mana pool."
