Toxicroak: I just really like this  set, and wanted to build around it.

Primarina: A nice special attacker, running some coverage options for a few threats I was told in the UU chat

Latias: A very useful support set that can also function in OU. Generally useful for doing considerable damage but also keeping things healthy.
Slowbro: Needed more physical defense, and Slowbro is a versatile option, being able to absorb damage due to stats and Regen, but also able to stop some threats and get burns.
Krookodile: Fast physical attacker, set mostly either from chat or analysis and build to hit hard and outspeed as much as possible.

Raikou: Fast special attacer, but a somewhat creative set I decide to run having been told that Scizor is practically a must-pick mon and my team can still deal with the threats HP Ice is meant to cover, in my opinion. Essentially a gimmicky twist on a standard set.
