How about auras to counter or rather eliminate the auras of opponents using the celestial spells? I mean, we have things like fortify, and all these zero pip cost auras. What about some nice 1 to 2 pip offensive auras like:
Lunar fog 2 pips for four turns, opponents attacks to -25 less damage.
Or
Suns heat:
1 pip, for four turns, attacks to opponent do +25 more damage.
Black hole:
2 pips: All charms and wards are removed from all players
