Short man mewtwo- when can you do it with 4?

I'd add any lv 40 Shadow ball mewtwo agaisnt all sets or lv 40 SC or hex gengar agaisnt non confusion if you have those available

Lvl 35 ttars and maxed dragons (neutral) are viable with ultra friends bonus. You will need fast max revive and relobby. Good gengars can help as well.

Making a team of 6 leveled up 35+ Ttars can do the trick. Just make sure it’s not Focus Blast and make sure someone is always in when you heal your team for round two.

From experience, with UF/BF bonuses, teams of maxed Ttars easily beat every non-FB moveset with time to spare.

C/FB, especially boosted, is stupidly hard. 2 rejoins is unavoidable unless your team is 6 maxed SB Mewtwos and everyone needs to have a pretty top-notch team to if you want to succeed with 4 players.
