Orvar, the All-Form + Great Whale + Imps' Taunt

Orvar, the All-Form

Great Whale

Imps' Taunt

How it works

1. Activate up to seven lands you control by tapping them, adding at least 4.
2. Cast Imps' Taunt with buyback by paying 4, targeting Great Whale.
3. Orvar's first ability triggers, creating a token copy of Great Whale.
4. When the Great Whale token enters the battlefield, it triggers, untapping up to seven lands.
5. Resolve Imps' Taunt, returning it to your hand.
6. Repeat.
7. If you control up to seven lands that can tap to produce at least 5, this combo nets infinite mana, which you can then target any creatures you control in step 2 to create infinite token copies of them.
