vampires
Bats can fly there buddy.
As far as I know, the Vampires in Elements haven't ever turned into bats.
ah damn internet prevented me from posting earlier, I was gonna suggest that some units are flying (obviously dragons)
but even then this will destroy most decks
most fractual decks, life rush, vampires
and yatta yatta
edit: it would make sense that rustlers/ leaf dragon can't fly cause its supposed to be in trees/ absorbing sun
I completely agree with the statement on Rustlers, as the only thing looking remotely like a wing on them is their little leaf things off the arms, which would never enable it to fly (Too small, and the upped one is bending).
For those curious, I compiled a list of the FGs that would (Probably) use flying creatures:
Chaos Lord (Mutants, Dragon
Dark matter (Archangels and Dragons, Chargers ignore it)
Destiny (Mutants/Hatches, and maybe Maxwell)
Elidnis (Just the Dragon)
Ferox (Just the Dragon)
Fire queen (Everything but Fahren)
Gemini (Just the Dragon+Momentum'd Recluses)
Hermes (Just the Dragon)
Miracle (Everything but Leaf Dragon)
Morte (Just the Archangels and RoLs, maybe the Dragon)
Obliterator (Stone Dragon can fly?...)
Octane (Everything)
Paradox (RoLs, and doubtful Dejas)
Scorpio (Just the Dragon, but Poison kills you too)
Seism (Same as Obliterator)
Eternal Phoenix (Everything)
Neptune (The Dragon)
