Dovescape + Guile

Dovescape

Guile

How it works

1. Cast any noncreature spell from your hand by paying its mana cost.
2. Dovescape triggers, exiling the spell, causing you to cast the spell without paying its mana cost, and creating a number of 1/1 Bird creature tokens equal to the spell's mana value.
3. Repeat step 2.
