Considering Earth already has pillar-specific control, I'm not really up for it.
I'm certainly up for moving it to a different element if that is the general consensus and someone can think where it would fit better... maybe gravity?
...On the other hand, many elements have more than one means of doing a similar task in slightly different ways:
-Time has several drawing cards: hourglass, sundial, precognition + nymph.
-Fire has several creature controls: RoF, Fire bolt, Rage Potion + nymph, Fire Shield
-Light has multiple ways to heal creatures and players: Holy light, Angels, Luciferin, Sanctuary
-Water has multiple ways to provide the freeze effect: Freeze, ice bolt, squid, ice shield
Currently, earthquake and tsunami are the only 2 effects that target pillars specifically. Permanent destruction works too but is a bit ineffective in comparison. In either case, though, it is accomplished by destroying the pillars. This card provides a new avenue of pillar control that is different from outright card destruction. Its akin to quanta control, but for pillars.
