>>18685820Better to have 252 hp than split it like that on defenses with Aegislash. You might also want to try special Aegislash instead of physical. This was the one I ran with my Charizard Y.
252+ satk, 240 hp, 16 atk, - speed nature
Shadow Ball
King's Shield
Sacred Sword
Pursuit/Shadow Sneak/Toxic
Don't put 4 hp evs on Charizard. Put those on def to make his health odd number (so you lose 49% health on stealth rock the first time you switch in).
What's with the Satk on Mandibuzz? Put those to defense and make it Impish if you want to run Knock off on it. If you don't have any move that will benefit from its attack, make it Bold with 0 attack IVs.
I'm not well versed in using Trevenant but won't it serve you better to make it defensive since you do most of the damage with leech seed and burns anyway?
There will be more times where Thick Fat Mamoswine will help you more than Oblivious.
