Banette ex + Muk

[Dark_Jirachi]

I think that this combo worth a try.
Use Muk to stop all power in play and do some disruption while burning supporters like hell.
When it is ready, send Banette up to do 90+10 per turn.
Muk also covers Banette against Shirtry ex as it is weak to Grass and has free retreat.

Not needed IMHO. Banette is nasty by itself. T2, you can burn a supporter using a holon supporter, move a damage counter, and KO a 50HP basic. T3 Banette's already doing 50 base for PC, play a supporter, move damage counter, hit for 60 if needed. T4, you could have Banette EX doing 80 if you've burned a supporter for a supporter or used a pokemon like CG Sableye to discard a supporter card from your deck.

I've tried using Banette EX as a mid-late game finisher, but it's so good that it can easily be a early-mid-late game finisher. Late game though, Banette's HP really becomes a big factor with OHKOs and stuff.
