'Landfall — Whenever a land you control enters, empower Jace 2. (Put two loyalty counters on a Jace token you control. If you don't control one, first create a blue Jace planeswalker token with "[−1]: Surveil 1" and "[−3]: Draw a card.")
Planeswalkers you control have "[−10]: Put a +1/+1 counter on target creature for each land you control."
