Been using this on PTCG Live and have a very high win rate against most top meta decks. 8-0 vs Lost Box. 3-0 vs Gardevoir. 2-1 vs Miraidon. 2-2 vs Chien-Pao. Open to any changes. All feedback is welcomed.
Update: Made 2 minor changes given the changing format. Removed 1 Tm: Evolution and Vitality Band and added 1 Super Rod and 1 Defiance band.
Snorlax stall isn't really a big problem here from what i've dealt with so far. Will tech in a Minior if i have to in the future. Xatu has been able to deal with the snorlax/mimikyu problems.
Haven't come up against Iron Valiant yet.
Charizard variants have a difficult time with well timed path to the peaks. If the charizard can set up 2 pidgeot fast, the deck becomes a problem for Mewtwo. The recommended path is to hold boss orders for the pidgey line. May consider a counter catcher or 2 for the future. 3-1 vs Charizard so far.
Lost Box has not been able to take a win off of this deck. Prioritizing the Mewtwo Vstar to kill off Giratina V & Vstars works wonders. Jirachi's ability hasn't come up too often outside of lost box. 12-0 vs lost box.
Gardevoir has not changed too much. Still able to take advantage of damage the deck deals to itself. 5-0 currently.
Miraidon has become a big problem for this deck with the Iron hands addition. 2-4 Currently my worst matchup.
