Gandalf, Shadow's Foe + Tiller Engine + Deadeye Navigator

Gandalf, Shadow's Foe

Tiller Engine

Deadeye Navigator

How it works

1. Activate up to three lands by tapping them, adding at least 1.
2. Activate Gandalf by paying 1, blinking it.
3. When Gandalf enters, its first ability and Deadeye Navigator's soulbond ability triggers.
4. Resolve the Deadeye Navigator trigger, repairing it and Gandalf.
5. Resolve the Gandalf trigger, blinking the lands tapped for mana in step 1.
6. When the lands enter, Tiller Engine and Gandalf's second ability each trigger three times.
7. Resolve all Tiller Engine triggers, untapping the lands that entered.
8. Resolve all Gandalf triggers, causing you to draw three cards and put three +1/+1 counters on Gandalf.
9. Repeat.
