Orvar, the All-Form + Clockspinning + Dockside Extortionist

Orvar, the All-Form

Clockspinning

Dockside Extortionist

How it works

1. Cast Clockspinning with buyback by paying 3, targeting Dockside Extortionist.
2. Orvar's first ability triggers, creating a token copy of Dockside Extortionist.
3. The token Dockside Extortionist enters the battlefield, creating at least five Treasure tokens.
4. Resolve Clockspinning, changing nothing and returning it to your hand.
5. Activate four Treasure tokens by tapping and sacrificing them, adding 3.
6. Repeat.
7. Once you have infinite mana, you can target any permanents you control in step 1 to create infinite token copies of them.
