Sentient Star
Turns out the small star at the core isn't like other stars...
Players set a Level. The Sentient Star Scenario counts as a Card belonging to no player with the chosen Level and the following effects:
(Harness Infinite Power) Whenever a player ends their turn, they may choose the highest-Level Card in play that isn't this Card and discard it.
(Doesn't Like Attention) Whenever a Card's effect reduces the Sentient Star's Level, that Card reduces its own level by the same amount after the effect has resolved. This cannot be prevented or countered in any way.
(Befriend A Star?) When this Card is reduced to negative Levels because of a Card's effect, the player controlling said Card takes the round. Otherwise, Sentient Star is set back to Level 0.
