Heatran, being able to wall Grass and Ghost attacks for Jellicent, constantly depends on it to take Water and Fighting moves aimed at itself. Like the Gengar-Heatran core, Jellicent can come in on Fighting types, like Keldeo that lack HP(Ghost), and ToxicStall them to death. Venusaur helps with the core to provide a LeechSeeding support as well as hazards. Opposing hazards outside of Stealthrock don't phaze Heatran much, up until its AirBalloon is gone. Anyways, here's the core:

Heatran@
Trait: FlashFire
Nature: Calm
252 Hp/ 248 Sp.Def/ 8 Sp.Attk
Flamethrower, EarthPower, Torment & Will-o-Wisp

Male forme

Jellicent@
Trait: WaterAbsorb
Nature: Bold
252 Hp/ 216 Def/ 44 Sp.Def
Scald/NightShade, Toxic, Taunt & Recover

*If you want to critique the core, at least try it out first. Don't just assume it doesn't work. Thanks! Enjoy! :)

Breloom seems like a big threat, low sweep OHKOes heatran and off the top of my head i dont remember how many bullet seeds need to hit to KO jellicent. Also landorus i seems to really threaten this core too as earth power 2hkos jelly so it cant switch in. I would suggest sp defensive celebi as its 3hkoed by hp ice, and can KO back with HP ice, as well as one of the best breloom counters.
