Durant vs. Eels/MEZ Setting up Eel in this matchup is a really bad idea, also you have Durant vs. MEZ as a 70-40 matchup....
Lol, Glaceon explained why setting up Eel is a good idea
6 Corners vs. Eels. In my testing this is far in Eels favor so long as you use a quick Zekrom EX/Magnezone to kill anything dangerous (Terrakion, Mewtwo with a bunch of energy, that's about it) then simply finish up with Zekrom (EX) or Thundurus.
They can easily take easy KOs and slow down your set up. They make a quick Zekrom really hard
6 Corners vs. Chandeplume. You state that if Chandeplume gets a decent hand and stays aware of Absol, they should take the game. That seems like it should be advantageous for Chandeplume and not 6 Corners, no?
It's actually pretty even because 6 Corners can constantly damage Chandelures and waste Blisseys. They can also Kyurem Spread to be really annoying
6 Corners vs. MEZ Why in the world would you attack with Mewtwo primarily? Attack with Zekrom EX primarily to get OHKOs, Catcher anything with energy on it, use your Mewtwo against opponent Mewtwo and that's it. I feel its in favor of MEZ if you do that but I'd need to test it more.
But, Terrakion schools Zekrom EX. Mewtwo can also easily take out their attackers with energies, which is your main objective.
Reshiboar EX vs. Tyram I feel this is advantageous for Reshiboar EX because first of all, its faster, needing only 1 stage 2, and secondly, its less weak to Catcher, being able to OHKO the opponent's stage 2s while avoiding the OHKOs on your own and using Switch.
But, Tyram is much faster and can consistently get out Typhlosions. Tyram will constantly get 2 or OHKOs on EXs and will win much faster.
Reshiboar EX vs. Chandeplume Personally, I wouldn't even set up Emboar unless the opponent isn't running energy. Just charge up a single Reshiram EX and take OHKOs with it, set up another if the first one gets close to dying/they can Eerie Light soon, and Chandeplume should suffer from the OHKOs. Not sure about the actual odds though due to lack of testing.
But this is hard, especially because they can use an attacker (Which good ChandyPlume decks play) to easily KO Reshiram EX) You will be forced to set up Emboar to set up quicker
Eels vs. Chandeplume In my testing, this is pretty much a dead 50-50 without ND. I would think Zekrom EX would make the matchup advantageous if anything since it can take OHKOs without Lost Zoning energy.
I guess, but if ChandyPlume plays Aipom the game is pretty much over already
Missing a number for MTC vs. Chandeplume.
Will fix that
I haven't tested all of the other matchups so I'm not sure how to critique them.
