So I"ve been playing a bit more (still fairly new), and I have a few questions to ask.
1) I understand that Alomomola isn't invulnerable, but, god damn, does it take a headache to take down. Serperior and Electrics don't fit on my ladder team very well, so could someone please tell me ways to take down this FUCKING BITCH without the use of a Grass-type or Electric-type?
EDIT: Cresselia's a fuckin' bitch, too. Can someone tell me how I can take it down?
2) Crawdaunt isn't too splashable because this is a game where every team member is precious. Could someone tell me good comrades for Crawdaunt?
3) I would appreciate it if someone would tell me if Breloom and Talonflame are good in OU, and why. The answer I got last time was somewhat vague. If someone would also tell me good comrades for them, too, that would be awesome.
1) The easiest way to wear down these Pokémon is probably status. Alomomola and Cresselia definitely don't appreciate residual damage or paralysis. Also, both of these Pokémon are very passive, meaning that you can easily use setup moves such as Dragon Dance and Swords Dance against them. Beware of Scald burns and Thunder Wave though (if you're using a physical attacker, Substitute might be useful as these Pokémon are typically too weak to break it).
2) Crawdaunt does really well against stall because of how powerful it is. I recommend pairing it with a faster Pokémon such as Mega Lopunny, allowing it to beat offense more easily. A slow U-Turn user such as Landorus-T might also help, because Crawdaunt can be very effective if it's brought in safely.
About your comment on "every team member being precious", this is only true for stall, which needs Pokémon like Mega Sableye, Amoonguss, and Skarmory, or else it will lose to certain things. On the other extreme, hyper offense involves sacrificing Pokémon instead of switching them out, as the goal of the team is to apply constant pressure.
3) What makes Breloom good in OU is the amount of pressure it applies. If it finds something slower, the opponent has to deal with the fact that it
will put something to sleep with Spore. Having one Pokémon asleep can be very dangerous for some teams, and even then, they still have to deal with Breloom's impressive power and coverage. It's not very good if it isn't used well, but a well-played Breloom can cause tons of damage to some teams.
Talonflame, on the other hand, is different: Although it struggles with stuff like Tyranitar, it can break through some sets with access to Will-O-Wisp, and it can do fantastic against stall. Its offensive set is infamous for priority Brave Bird, which can easily revenge kill stuff like Mega Lopunny, Mega Gallade, Volcarona, and Mega Venusaur. One of the only things that hold it back is a 4x weakness to Stealth Rock, making hazard removal necessary on any team it's on, but when your side of the field is clear of hazards, Talonflame can easily put in work.
