Almost every deck has Fallen Druid and/or Eternity, so Armagios and Massive Dragons are easy enough to deal with. CCYB doesn't, but it has enough damage to power through gravity pull. The biggest threat is that Chimera will add up to over 100 damage ignoring shields, but I don't think that many creatures can be played before they're controlled.
It's ironic to be designing FG's to counter anti-FG decks, which were designed to counter FG's.
