I remade the deck. It works better now, and can even stand up to early Devourers (the bane of the deck before).
Mark of Gravity
4x Gravity Tower
11x Aether Tower
6x Elite Charger
6x Twin Universe
3x Thunderbolts
30 cards
The bolts were there to finish off the opponent late game, if needed, but to also get rid of early threats (Devourers, Otys, Mind Flayers, Fallen Elves, etc). It works SO much better now, though it is still pretty basic and boring. Sundials pose a threat, still, and so does double Firestorm (which is what killed it in t50 ONCE), but it wins pretty often. o-o
