MegaGallade ily for giving torterra shell smash, but aren't you worried tree turtle would be quite overpowered? Since it had nice physical attack and reliable recovery?
Torterra is PU. Giving it Shell Smash makes sense flavour-wise (It has a shell, what more is there to say), and makes it more viable.
There is Skarmory, however, which can wall Torterra due to the fact it is immune to EQ, resists Wood Hammer, and only move that can
try to hit it is SuperPower, which lowers Torterra's attack and defenses anyway, and even that is a 3HKO after leftovers.
+2 252+ Atk Torterra Superpower vs. 252 HP / 252+ Def Skarmory: 144-170 (43.1 - 50.8%) -- guaranteed 3HKO after Leftovers recovery
+2 252+ Atk Torterra Stone Edge vs. 252 HP / 252+ Def Skarmory: 120-142 (35.9 - 42.5%) -- 95.1% chance to 3HKO after Leftovers recovery
0 Atk Skarmory Brave Bird vs. -1 0 HP / 4 Def Torterra: 308-366 (93 - 110.5%) -- 62.5% chance to OHKO
0 Atk Skarmory Brave Bird vs. 0 HP / 4 Def Torterra: 204-242 (61.6 - 73.1%) -- guaranteed 2HKO after Leftovers recovery
It does get Solid Rock, however. Then again,
8 Atk Avalugg Avalanche vs. 0 HP / 0 Def Solid Rock Torterra: 432-507 (130.5 - 153.1%) -- guaranteed OHKO
+2 252 Atk Torterra Superpower vs. 248 HP / 252+ Def Avalugg: 214-252 (54.4 - 64.1%) -- guaranteed 2HKO after Leftovers recovery
Sure, it's a threat, but not much so that it needs banning, imo. If you're scared of it, use Skarm or rather Avalugg.
I'm in progress of making a big update for this pet mod anyway. It's quite outdated, and even I question myself for some of the features here. It's taking a while, due to all these inspirations and ideas popping up in my head. If anything, I might as well make a check for Torterra.
Thanks for the feedback. :]
