Tangled Colony + Phyrexian Altar + Deadeye Navigator + Shivan Meteor + Skullwinder

Tangled Colony

Phyrexian Altar

Deadeye Navigator

Shivan Meteor

Skullwinder

How it works

1. Cast Shivan Meteor by paying 3, dealing 13 damage to Tangled Colony.
2. Tangled Colony dies as a state-based action due to having less than 0 toughness.
3. Tangled Colony triggers, creating thirteen 1/1 Rat creature tokens.
4. Activate Phyrexian Altar eleven times by sacrificing eleven Rats, adding 6.
5. Activate Skullwinder by paying 1, blinking it.
6. When Skullwinder enters the battlefield, it and Deadeye Navigator's soulbond ability trigger.
7. Resolve the Deadeye Navigator trigger, repairing it and Skullwinder.
8. Resolve the Skullwinder trigger, returning Tangled Colony to your hand from your graveyard, and cause an opponent to return a card from their graveyard to their hand.
9. Repeat from step 5 one additional time, returning Shivan Meteor to your hand using Skullwinder instead.
10. Cast Tangled Colony by paying 1.
11. Repeat.

This intricate loop centers around funneling massive overkill damage into Tangled Colony with Shivan Meteor to generate a horde of thirteen Rat tokens upon its death. Phyrexian Altar immediately converts these disposable tokens into the exact colors of mana needed to fuel the engine, while Deadeye Navigator provides the blinking engine itself via soulbond. Finally, Skullwinder recycles your destroyed combo pieces—bringing back both Tangled Colony and Shivan Meteor from the graveyard to your hand—allowing you to recast them and repeat the entire cycle for infinite value.
