From this Hall Run:
I get 6 CC, stockpiled.
Zweilous gets 6 EC, uses 3 of them as EC (9/9, evolves) and the rest as MC (goes to 7).
Gains Tri Attack from evolving, Flamethrower, Surf and Charge Beam as TM moves (-2*3, 1 MC remaining),
Hydreigon Typhon (M)
Nature: Rash(+Sp.Atk, -Sp.Def)
Type:
Dark:Dark STAB; Immunity to all telepathic and telekinetic attacks, better performance in all darkened and especially twilight conditions. Can use any Dark-type attack regardless of Attraction.
Dragon:Dragon STAB; more in touch with legendary or special auras in arenas. Able to use Thrash without losing focus.
Ability:Levitate(Innate)This Pokemon naturally floats above the earth when released or easily takes flight, evading all the seismic moves. Earth Power will have 3 less BAP. Dig and Dive can still strike a Levitating Pokemon, but only if their user is over Size Class 4, has Levitate, is 3.5m or larger, or is a Flying-type. Other Ground moves can still hit.
