Gandalf, Shadow's Foe + Tiller Engine + Emiel the Blessed

Gandalf, Shadow's Foe

Tiller Engine

Emiel the Blessed

How it works

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