Tess Nova

Defender
When Tess Nova enters the battlefield, choose an ability:
Reality Manipulation — whenever an opponent enters their combat stage, after they have attacked you may attack as well, and all creatures under your control gain vigilance.
NPC Summoning — whenever a creature enters the battlefield not under your control, create a {x}/{x} NPC creature token where {x} is equal to their creature's {c} mana value.
