Something I nommed made it into the top 10? nice
Landorus-I
Want to stop it? Better be carrying multiple coverage specific checks, because if it has the coverage for your already very few options to answer this monster, you either hoped you had something faster and it was "just" AoA or clicked X tbh
Manaphy
Basically, you prayed to Arceus Manaphy didn't have the set that destroyed your team if you were slower. Otherwise, you prayed you were faster and could KO or you were screwed pm
PS: fuck Goth
Deo-S
It made HO a lot more viable than it probably should have been, and it did this by stacking rocks and multiple layers of spikes oftentimes on suicide lead sets. It could potentially get around Magic Bounce via Skill Swap to boot (not that it was that relevant at the time, MDia and MSab came out after it was banned), and at worst got rocks up. Not to mention it had a decent offensive set with (mixed) coverage up the wazoo (pretty much Greninja level coverage, maybe more so) and a 140 base power STAB attack. Oh yeah and it outpaced everything up to and including ScarfChomp.
