>>22890071>95/155/105 defensesThe stats make sense; Torterra's a Pokemon in need of serious help to stand out
>1x IceIt's technically 2x
>spamming leech seedNo one seems to have a problem with M-Venusaur
But I agree, it's a broken ability. Thick Fat's already Venusaur's gig too so that's not really an option. I'd say Solid Rock; it's basically as good as it can get defensively without being broken. Don't forget it has access to Stockpile too to boost both its defenses and Curse to become a physical wall.
Going off the 95/155/115 spread from a few days ago:
252 SpA Life Orb Protean Greninja Ice Beam vs. 252 HP / 252+ SpD Solid Rock Mega Torterra: 320-378 (81.2 - 95.9%) -- guaranteed 2HKO
252+ Atk Choice Band Talonflame Brave Bird vs. 252 HP / 0 Def Solid Rock Mega Torterra: 240-285 (60.9 - 72.3%) -- guaranteed 2HKO
252+ Atk Tough Claws Mega Charizard X Flare Blitz vs. 252 HP / 0 Def Solid Rock Mega Torterra: 294-348 (74.6 - 88.3%) -- guaranteed 2HKO
In each case Torterra can OHKO back. Mega Abomasnow is the only mon able to guarantee OHKO:
252+ SpA Mega Abomasnow Blizzard vs. 252 HP / 252+ SpD Solid Rock Torterra: 396-468 (100.5 - 118.7%) -- guaranteed OHKO
Mold Breaker clones also get it, but that's still only a small number of Pokemon.
