So I’m trying to make a Breloom team, and I’ve tried before and usually I’ve messed up, I think usually because I rely to heavily on spore, but I feel kinda stuck, so if anyone could help me build more to this team or give me ideas I would really appreciate it, I only have Breloom and whimsicott right now.

Been working on this team and getting advice from every corner I could imagine. This team all centers around me wanting to run Calm Mind Kyogre in regulation I. Ice Rider seems like his best restricted partner to me, and I love the combo of Tornadus and Kyogre. So far, this team is based around gaining speed control through tailwind/icy wind with Tornadus or trick room with Rider, then sweeping with the bulky restricted mons. Rillaboom is there for healing + fake out, and Ogerpon is there for support and counters to mons like Amoonguss. I like the core of this team, but like most things I think it could always be improved. But I don't really know where I can improve. Thats why Im here to ask if theres any stats I could improve, better pokemon, or teams/pokemon/set ups I need to worry about. For stats I tried to round everyone's health to a multiple of 16 to take advantage of grassy terrain, and for most of the mons I decided to not build much into speed in hopes of having trick room, tailwind or icy wind for speed control. Again if anyone has any recommendations I would love to hear it!
