Whirler Rogue + Deadeye Navigator + Phyrexian Altar

Whirler Rogue

Deadeye Navigator

Phyrexian Altar

How it works

1. Activate Whirler Rogue by paying 1, blinking itself.
2. Whirler Rogue enters the battlefield, triggering itself and Deadeye Navigator's soulbond ability.
3. Resolve the Whirler Rogue trigger, creating two 1/1 Thopter artifact creature tokens.
4. Resolve the Deadeye Navigator trigger, repairing it and Whirler Rogue.
5. Activate Phyrexian Altar by sacrificing both Thopters, adding 1.
6. Repeat.
