Shiko, Paragon of the Way + Pull from Eternity + Another Round + Swarm Intelligence

Shiko, Paragon of the Way

Pull from Eternity

Another Round

Swarm Intelligence

How it works

1. Cast Shiko either from your hand or from the command zone by paying 2 plus commander tax, if applicable.
2. When Shiko enters the battlefield, it triggers, exiling Another Round from your graveyard and casting a copy of it without paying its mana cost.
3. Swarm Intelligence triggers, copying the Another Round spell.
4. Resolve the first copy of Another Round, blinking Shiko.
5. When Shiko enters the battlefield, it triggers, exiling Pull from Eternity from your graveyard and casting a copy of it without paying its mana cost.
6. Swarm Intelligence triggers, copying the Pull from Eternity spell.
7. Resolve both copies of Pull from Eternity, returning the original Pull from Eternity and Another Round from exile to your graveyard.
8. Resolve the second copy of Another Round from step 2, blinking Shiko.
9. Repeat from step 2.
