Phantom Steed + Temporal Manipulation + Shipwreck Dowser

Phantom Steed

Temporal Manipulation

Shipwreck Dowser

How it works

1. Cast Temporal Manipulation, taking an extra turn after this one.
2. Attack with Phantom Steed.
3. Phantom Steed triggers, creating a token copy of Shipwreck Dowser that is tapped and attacking.
4. Shipwreck Dowser enters, returning Temporal Manipulation from your graveyard to your hand.
5. Pass the turn.
6. Repeat.

This elegant loop revolves around chaining extra turns while continuously recurring your spells. By casting Temporal Manipulation, you secure the extra turns you need, which then gives you the window to attack with Phantom Steed. Each time Phantom Steed charges into battle, its attack trigger spawns an attacking token copy of Shipwreck Dowser. The newly arrived Shipwreck Dowser leverages its entry ability to scoop Temporal Manipulation right back out of your graveyard, letting you recast it on your extra turn to do it all over again.
