Well, I am mostly a
player, but my favourite
card goes for
Gravity Pull. It is surprising good as an instant creature killer and it can be used both offensively and defensively.
Chimera is my second best card. For all those who may complain that it dies right away due to it's gravity pull ability, here is a tip:
* First of all, have a lot of creatures on field, have a Chiemera, Gravity Pull and another cheap creature card (upped Graviton Mercenary) on hand and enough
quantum to perform the strategy below.
* Summon the Chimera (it will absorb all your creatures on field).
* Summon the cheap creature (in our case, the 2
upped Graviton Mercenary).
* Cast Gravity Pull onto your Graviton Guard.
* Well done! Now, you have a powerful Chimera with Momentum but not gravity pull onto it and a Graviton Guard ready to absorb your next 5 damage. A bit of tricky and it needs 3 cards to work, but it often worths the effort.
