Bagon Concerns

Do you actually need a Salamence for Mewtwo? Previous posts made it sound like you get by well enough without it. There's no real harm in holding onto it, especially if you already have a Salamence for the Pokedex at least.

EDIT: From my experience, I have one Salamence that saw lots of use in Lati raids, possibly Rayquaza ones, and gets thrown in gyms on the regular for style points and candy chances. I say possibly Rayquaza because I don't remember if I evolved it before he left or not. He's my only one and right now that' enough for me. I have two 15a Bagon I'm keeping for a potential community day. Unless you absolutely need it now I'd advise keeping it for later.

Don't consider Beldum confirmed until the forthcoming announcement

Well, if you evolve it for Mewtwo, you're likely to have no use for it in many of the Raids as the Mewtwo will have Ice Beam and your Salamence likely won't last more than 2 Charged Attacks - and to get a useful attack out, you'll need Draco Meteor (no other move is going to be of any real use), so it's possible that your Salamence will faint without using a single Charged move in the raid. So... might not be a good investment against Mewtwo.

Against Deoxys it will probably have far more use, particularly if the Deoxys has Counter as a quick move (which will decimate Tyranitar lineups). But even then, Salamence isn't likely going to be a decent counter against Deoxys because of how hard it will be to get a Draco Meteor off - again, Salamence is likely to end a significant number of Raids without getting a single Charged Move off.

Mostly, I'd advise waiting for CD and see if they give Salamence Outrage. Or some other 2-bar Charged Move; 1 bar charged moves are great... but you have to survive long enough to use them. That's tough against opponents with 300+/- Attack like Mewtwo and Deoxys.

I never use my Salamence, and it never shows up as a top attacker against anything I meet. Save your Bagons.

Just do it!

I have only evolved into one Salamance because I caught a boosted Level 35 82% Bagon, and haven’t used any stardust on it. If it learned outrage I would use it, but Rayquaza is better in every way vs Salamance, and I have more Rayquaza candy.

I would save until a CD comes up. I haven’t used my Salamance and would rather use Dragonite or Rayquaza for the Gen IV raid bosses.

I don't think evolving Salamence is that risky. If we get a Bagon community day, the best current move they could give it would be Outrage, and introducing anything better than Outrage would outclass Rayquaza in DPS, which they probably don't want to do.

That said, I also don't think it's that necessary for raiding Mewtwo. You need for the weather to be windy and even then the Dragons only really shine against FB and FT. Salamence is the frailest of them and is limited to 1-bar DM, which makes it super risky against boosted Confusion. If you want more Dragons, I'd try to make more Dragonites, but in general just develop your Tyranitar team.

EDIT: I've had a maxed Salamence for a long time and Latis were the last time I used it for group raids. It might get a spot in my Mewtwo team if I go against FB in windy but only then.

Save it. We don’t know for sure if we’ll get Bagon or Ralts Community Day but if we do you’ll probably want their exclusive moves. Salamence can deal quite a bit of damage, particularly in Windy weather, but as you’ve said in previous posts, you’re probably better off using Dragonite. An Ice Beam variant would trash Salamence.

My team for Mewtwo looks like this:
SC Gengar
SB Mewtwo
2x B/C Tyranitar
Houndoom
Filler

In Windy weather I switch Gengar for something else and lead with Mewtwo, I’ve been using Sky Attack Moltres fairly often, it hits like a truck and resists some of the moves, making up for its lack of bulk.

I have been waiting for bot Salamence and Metagross because I don't like the choices for their available moves.

Salamence has higher attack and lower defense than Dragonite. It should have received moves that made dodging easier. Dragon Breath/Dragon Claw would have been awesome. Dragon Claw has less brute power than Outrage, but Salamence has that higher attack stat to compensate.

Steel moves just suck and anything that I might need to use it against I usually use weather boosted fire types, so don't really have a need for Metagross.

I posted a similar question a few days ago asking if we should keep Bagon until its CD, as my wife got a luck level 30 ADS 151512 Bagon and planned to evolve it to Salamence. That post is before the mega release of M2 so the majority of voice is keeping it for a chance of CD and a more powerful move (I remember some friend mentioned moves like Fly and something else). And as a result I successfully persuade my wife to keep her Bagon at the stage of Shelgon and wait. Right now although M2's release may change the situatio a little bit, but there could be other or better options for the team build-up in any case. I would still say keep it for the potential CD.

Agree with many that it is a good idea to keep it and save it for a future CD, unless you need it now. I have not had much luck with either bagon or beldum and have not evolved either, saving candy till I get a good candidate. Recently I obtained a lucky 91% bagon (14A13D14S), but I am resisting developing it awaiting a possible CD (but I have enough dragons as is with five maxed out Dragonite and Rayquaza).
