For instance Mr. Grumpers from the Kitty Cat faction says
Choose a minion. It has -2 power until the end of the turn
Can a minion be rendered with negative power, or is it always at least zero as one might expect in a realistic attack situation--you know, one of Zombies, Pirates, Dinosaurs and Kitty Cats attacking an alien home world.
Glymmer from the Fairy faction has this power
Talent: Until the start of your next turn, either another minion has -4 power (minimum power 0), OR this minion has +1 power.
Can I play Glymmer, and then, on my next turn, use his talent to force another minion to 0 power, then play Mr Grumpers to send him to -2 because there is no "minimum power 0" clause in Mr. Grumpers?
