Who is your go to Pokémon for clearing gyms?

Now starting to use my maxed two bar attackers more to build up victories instead of using the ideal specialist. Mewtwo, Raikou, Dragonite, Gengar...plus they are not relevant for raiding this week, so if I forget to rehealth them not a big deal.

When gyms aren't stacked with normal-type tanks, my go-to is usually Mewtwo since confusion hits like a truck, and shadow ball is resisted by very few. My other go-to generalists are Rayquaza and Latios.

Dark Tyranitar sets, kyogre, Scizor

Dragonite, Tyranitar, Lugia, Machamp, Mewtwo, Charziad, Venesaur.

It’s been Partly Cloudy for like a week, so I’ve been enjoying all rock Tyranitar.

Lugia as of late. I enjoy it’s performance. Tanky, great set for dodging and it isn’t really in danger of timing out against Blissey. Typing is also good, narrowly resisted

I like Mew (Snarl + Rock Slide) for general clearing, it works pretty fast against quite a lot of types, it last long and you rarely have to switch.
But when in a hurry I just go with the game's suggestion which is often a Kyogre or Tyranitar.

I also find Latios great for clearing demotivated/disposable defenders, when boosted ttar is also good.

My standard preset gym buster team has a focus blast Mewtwo that is my Blissey killer then after that I have a DB DC Latios as my general sweeper followed by a Kyogre, Entei, Raikou and B/S Tyranitar which I will use as counters when there are high motivation targets.

I usually still use Machamp due to the order of my Battle Party, but if I fight something strong, that resists his attacks (Gyarados, Dragonite, Gardevoir, etc) I quickly switch to Mewtwo or Rayquaza (usually vs dragonite/salamence)

The 6th slot is only for collecting battles won on a specific mon - just in case (I pick only Pokemon that could/should get a normal, mega or primal evolution/form in future for this)

If no golden berry involved, and no high CP high motivation Blissey in gym, i just use wild catch pokemon at CP1000+, tier 3 or 4 raid boss from raid that dont have a good iv, or pokemon from mass evolve (at the time when i still do it, not a good iv legendaries when there is a double candy event ( i save them now for trading with my friend)
If i run out of those, i ussually just use the recomended party.

A gym that is not stacked with Normal-type tanks is very hard to find here, but in that case, I would use Dragonite (which remains the best non-legendary generalist, matched only by Tyranitar) or Gyarados (simply because I love it).

Autoselect is a damn fine Pokemon for me in that improbable scenario.

I have 6 maxed dragons, 24 tyranitar above lvl 35, a trio of maxed kyogre, a brigade of Rhydon, a smaller brigade of Golem, and a random assortment of maxed Mewtwo/Groudon/Ho-oh/Lugia/Moltres/Raikou/Espeon....

so whatever the game wants me to use, I'll use it

3 Machamps, 1 Dragonite, 1 Raikou, 1 Kyogre, 1 Zapdos. Depending on gym composition, 1 pokemon will be swapped out.

I love DB DC Latios. Other than that, I use Dragonite, Tyranitar, Raikou and Kyogre.

I use my Mew with Dragon Tail + Psyshock. It's fun to use and not resisted by many defenders. More fun since they fixed the animations to prioritise charge moves.

The trident: Espeon (Perfect Confusion), Gengar (Shadow), Tyranitar (Darkness).
