The idea is you send out Hitmontop and Kyruem first. If you're up against Kyogre wide guard and fusion bolt. If not, fake out/coaching on the Hitmontop and protect/attack on the Kyruem. Then if up against dragon types or a special attacker, switch Hitmontop to Tapu Fini. The misty terrain will half the damage a dragon move will do to Kyruem, along with the misty seed spdf boost plus the def boosts from Hitmontop.
The Incineroar is for steel and fairy type coverage along with dropping stats.
The Landorus is the special sweeper, and covers any physical walls the Kyruem can't break along with more coverage.
The Heatran was meant to cover weaknesses and provide Will-O-Wisp support to halve physical damage, but it's proven to be a pretty useless addition other than Will-O-Wisp.
I've a spotty win-lose streak with this team, with losses that always come soooo close. If you have any advice or feedback, please let me know, because the close calls and losing fights that were in my favor is frustrating. Thanks.
