I REALLY like this. Aside from the two types of Pillars, it's really good (you really only need one or two Emerald Towers for it to work, but more is always good). A single Feral Bond will be stolen quickly, which means that you might have to waste an explosion on it, unless you save it for late game to get a one turn HP boost with a full-ish field. These problems can't really be avoided in a trio-deck, so all that aside, I think this would do pretty damn well in PvP.You need green quantum to produce Fireflies so one or two Towers is not enough. I would much rather have 7-8 Emerald Towers but there is no room for them.
