Rogue, Mutation Channeler

X-Gene — At the beginning of each combat,
Rogue, Mutation Channeler gains flying until
end of turn if a creature you control has flying.
The same is true for deathtouch, double strike,
first strike, haste, hexproof, lifelink, menace,
indestructible, menace, reach, skulk, trample,
and vigilance. If this spell was cast for its X-Gene
cost, count the above abilities found among
creatures on the battlefield instead.
(Count each ability only once.)
