I had 8 win streak with this trick room team.
Altaria is for weather blocks and free switch in to Charizard Y. But I haven't brought him that much. Breaking Swipe disrupts physical attackers with Incin.
Chandelure I dont really need to mega because of flash fire. He just presses TR and shadowball most of the time.
Mega Ampharos tanks most special attacks and with intimidate he tanks 2 Garchomp EQ. He OHKOes Charizard Y with Thunderbolt and OHKOes Archaludon with Focus Blast.
Incin is for intimidate fake out and vs Ghost types and sound users with throat chop.
Tinkaton is the Fairy killer with Giga Hammer and also Fake out.
Sinistcha another TR user that disrupts Gqrchomp and Aerodactyl.
I feel like Mega Ampharos has potential in Trick Room.
My loses was when I didn't bring Ampharos in the back and when they stop Trick Room.
