Jace enters the battlefield with six loyalty counters due to
Vorinclex.
Activate
Jace's third loyalty ability by removing five loyalty counters from it, creating two nonlegendary copies of
Jace that enter the battlefield with six loyalty counters each due to
Vorinclex.
Repeat step 3 using a
Jace token.
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.
