I suggest ditching either Alakazam or Haxorus. You need another Fire resist- prefferably a Water type to resist Ice as well.
Rotom would work nicely, maybe in lieu of Raikou. Resists Fire, Ice and is immune to Ground, and gives your team potential Support moves. Plus, it's the classic yet reliable Volt-Turner with Scizor.
Bulky Landorus-T, Donphan or Metagross all work pretty decently as potential Stealth Rockers. The last slot could be filled with either Alakazam, Haxorus (which might work decently as a pseudo-Double Dragon clean up crew), or another pokemon if your team ends up having trouble against anything in specific.
