All FGs have a "rush factor", meaning if they get the right cards they will destroy you, no matter what deck you have, because of all the other advantages they enjoy. Since all FGs have this ability, it is ignored when judging a FG's power level. "Easy" means easy relative to the other gods.
In fact, since Destiny doesn't have any heavy-hitters aside from the chance of Fate Eggs and mutants, the "rush factor" is less than a FG with heavy-hitters already in the deck, like Miracle's Light Dragons.
