Lae'zel, Vlaakith's Champion + Jace, Cunning Castaway + Carth the Lion

Lae'zel, Vlaakith's Champion

Jace, Cunning Castaway

Carth the Lion

How it works

1. Cast Jace by paying 1.
2. Jace enters the battlefield with four loyalty counters due to Lae'zel.
3. Activate Jace's third loyalty ability by removing four loyalty counters from it.
4. Jace dies as a state-based action due to having zero loyalty.
5. Resolve the Jace ability, creating two non-legendary copies of Jace, which enter with four loyalty counters each due to Lae'zel.
6. Repeat from step 3 using a Jace token.
7. Once you have infinite Jace tokens, you may activate their second loyalty abilities by removing two loyalty counters from them, creating infinite 2/2 Illusion creature tokens.
