Is there a pokemon you recommend for status moves to replace alakazam?
You have a few options there.
Breloom does well, being the only OU user of Spore. Though it'll give you another Fire weakness.
Breloom @ Toxic Orb
Poison Heal
Adamant [+Attack; -Special Attack]
12 HP / 244 Attack / 252 Speed
- Spore
- Substitute
- Focus Punch
- Seed Bomb
Some Specially Defensive Heatran sets have you throwing around Toxic / Will-O-Wisp.
Heatran @ Leftovers
Flash Fire
Calm [+Special Defense; -Attack]
248 HP / 252 Special Defense / 8 Speed
- Lava Plume
- Stealth Rock / Roar
- Protect
- Toxic / Will-O-Wisp
For your team however, I think Jellicent makes a good match.
Jellicent @ Leftovers
Water Absorb
Bold [+Defense; -Attack]
248 HP / 216 Defense / 44 Speed
- Scald / Surf
- Will-O-Wisp / Toxic
- Recover
- Taunt
Jellicent can shut down a lot of common offensive threats in OU, like Jirachi, Heatran, Politoed, and recovery reliant Dragonite -- something your team might have problems with -- and defensive threats like Hippowdon, Blissey, and Forretress.
