Actually, they can get a T4-5 with PGX, which my lead me to not run Pluff, instead, run a deck that can get rid of its Pokemon. Gigas does that amazingly, Junk Arm away my low Pokemon count, SSU benched, Junk Arm/Regimove away. If you have no bench and no Pokemon left in the deck, theres nothing they can do. Though no bench really hurts, because my build relys a lot on multiple Set-Ups, and Trade Off. But during one game, they couldn't win because I collector'd, then Junk Arm'd away all Pokemon in the deck. That sound very stupid, but if the only Pokemon not LZ'd or discarded is Gigas X, they can't do anything, unless the want to Level down, and hope for a lucky Judge/ Spiritomb TR, and the second I draw it I just level-up. Still, being unable to keep and Mespirt lock hurts (a ton), there is almost nothing they can do. Everyone will disagree with this method I know, but it does work.
