nice idea on making these spells...
as perms, it would be destructible, so yeah..
all creatures mutate then returns to normal after 2 turns?? (sounds good but coding might be a problem)
players return to 99 hp for two turns, then accumulated damage stays after 2 turns, returning to the normal HP (kinda weird, possibly making -hp)
players' hp gets reduced by X. X = total quanta ingame (your quanta + enemy quanta + creature/perm costs) for 2 turns.. (this sounds more of entropy/gravity)
on both sides of the field, summons a tornado for 2 turns. tornado puts permanents in time bubble OR summons a tornado for two turns. tornado takes up X creature slots, and randomly changes creature position. X = #of wind pillars/pends/towers + 3 (if ability #2, maybe delay random creatures if # of creatures > # of slot tornado uses up)
all creatures gain -X|+20 for 2 turns. X= average attack of all creatures on the board. can not drop attack below 0
these are all i have right now... anyways, gl & hf on card designing!!
