Hey, I just saw ur team and screenshot, so yeah, good job. Btw, as for the Bliss weakness, u can try Safeguard over Psychic on Volc, as now Bliss could have trouble at Toxic'ing it and Prim already deals with most walls Sylv has Mystical Fire so they both can compete a little :3 (nah just kidding with that part).
I experiment a lot, currently running:
28 HP / 176+ Atk / 40 Def / 120 SpD / 136 Speed
most replaceable is speed, the 136 neutral let’s you outspeed standard spDef Lando and all neutral aegislash/crawdaunt
I don’t run high horsepower or darkest lariat for coverage, close combat and rock slide have worked well so far!
