1. What about we change earthquake (including earthquake used by trident) to absorb/drain/whatever ALL quanta from the opponent's (always opponent) quanta pool from the element of the pillars? Like nymph's tears, quantum pillar would do 1 random element.
2. What about making it add one turn of freeze to every frozen creature when you play the card?
1. This sounds like a massively overpowered Black Hole. Earthquake already has a limit, and that is that it destroys only 3 towers, same with Black Hole, except that it removes 3 quanta per element. I don't think anyone would want a game-ender on a stick in the game (and I mean Trident).
2. This idea actually sounds good, but I think it would be even better if it froze any creature in the top and bottom rows, instead of just killing them. Of course, then Freeze/Congeal [and any cards that freeze (Ice/Permafrost, Ice bolt/Lance, Squid, and the card itself)] would need to be nerfed, and if that is the case, then I vote that creatures be given a 1 turn immunity after being frozen.
