Hmm... If that Implode card which is also in deck building stage was used in tandem with G. PIllars it'd be OP.
If I had 2 G. PIllars and 2 Implodes and 1 of these, then I pretty much do the impossible 20/0 and break the game. (assuming the upped version)
And even if not, by turn 2 or 3, I can get 10 or 7 pillars/pendulums for free with the above combo.
The problem is without Implode, it becomes quite useless, because Gravity has no pumpable spells (Fire Bolt in
)
The only way you can get a sizable amount of pillars is by using
, otherwise it's too slow and you'd get 1 at the most.
