Mewtwo Raid tomorrow, best DPS to use?
I'm only Level 22, but I got an EX Raid Pass for tomorrow. I'm sitting on 130K Stardust and have a handful of 1500 Alola Exeggutor, a 1400 Zapdos, a 1200 Articuno, and an Aron and Squirtle I could fully evolve and power up a few times. Also a 95 IV Aerodactyl with Bite for supereffective damage.
What are my best bets here to help out the Level 30-40 guys as much as possible?

Use your highest level pokemon, as long as they hit for neutral/supereffective damage.
You should save the stardust to power up this Mewtwo, if you are casual then its the best investment. Actually its the best investment even if you are hardcore :).
Like they said already, let the others kill the Mewtwo, you just hit with what you have. Alolan Exeggutor is a good option, Use Solarbeam, its OP.
Most of the Mons you mention don't match up well with Mewtwo. If you don't have any of the Mons I mention below, then use your highest DPS attackers. The answer really comes down to: "will the Mewtwo have the Charge Move Focus Blast (Fighting) or something else"?.
1) A double dark Tyranitar / Houndoom is a top counter for NON Focus blast (ie 3 of the 4 Charge Moves). So if you have these assume these will be your best option, but they should be Bite and Crunch / Foul Play. These Mons resist Psychic attacks so will resist M2's two psychic Fast Moves and will resist a Psychic charge Move if you get lucky and get this.
2) If you are unlucky you will get a Focus Blast M2 which will wipeout TTAR and HD with a single hit, thus better to use Gengar or a high DPS generalist like Dragonite / Rayquazza / Kyogre / Gyarados. Lugia is a safe option for FB which it strongly resists, but LUGIA does less than optimal damage vs M2.
If this is your first Mewtwo you may not know right away what move it has but you can ask one of the more experienced raiders (who should know based on the auto select menu). Good luck, you probably will get a good Mewtwo ... first timers often get the good ones!
