Because it's not Mega Venusaur.
Roserade has always been one of my favorite grass types, and there's a few good reasons why:
1. She has hair like Kakashi Hataki.
2. She has a mask. AND a cape.
3. No other grass type plays the same way.
As far as number 3 goes, allow me to explain.
Venusaur, in the past, was a Chlorophyll sweeper. Amoonguss thrives on stall, and Tangrowth walls you to deal. Ferrothorn does whatever the fuck Ferrothorn does, and Breloom smashes faces (or stalls if you're into that). What ROSERADE does, though, is aggressively hazard stack, and destroy whatever tries to stop it with its nearly-unmatched SAtk (for a Grass-type, anyway).
Or, anyway, that's what it USED to do. The power creep of this generation has been a bit strenuous on our masquerading flower girl, and she has little use outside of UU. Hazard stacking is best left to the Deos, Mega Venusaur hits almost as hard and is vastly bulkier, and Amoonguss brutally outclasses her on stall with Regenerator. So what's Roserade to do?
In my opinion, exactly what she used to, only better. Well, to an extent. Hazard stacking, I'm afraid, will never be her selling point in OU, but a couple of other things might, beginning with:
She has the highest SAtk stat out of any Grass type.
Yes, it's true, her Leaf Storm is something to be feared, as it's going to take a huge chunk out of anything that doesn't resist it (bar the blobs):
252+ SpA Mega Roserade Leaf Storm vs. 4 HP / 0 SpD Garchomp: 319-376 (89.1 - 105%) -- 31.3% chance to OHKO
252+ Mega SpA Roserade Leaf Storm vs. 4 HP / 0 SpD Excadrill: 396-466 (109.3 - 128.7%) -- guaranteed OHKO
252+ SpA Mega Roserade Leaf Storm vs. 252 HP / 0 SpD Gliscor: 354-417 (100 - 117.7%) -- guaranteed OHKO
and just for fun:
252+ SpA Mega Roserade Leaf Storm vs. 252 HP / 0 SpD Quagsire: 1584-1864 (402 - 473%) -- guaranteed OHKO
Her Sludge Bomb is also quite powerful:
52+ SpA Roserade Sludge Bomb vs. 252 HP / 252 SpD Mega Venusaur: 135-160 (37 - 43.9%) -- guaranteed 3HKO
And that's to Mega Venusaur, mind you.
HP Fire, as coverage is always good:
252+ SpA Roserade Hidden Power Fire vs. 252 HP / 0 SpD Ferrothorn: 304-360 (86.3 - 102.2%) -- 18.8% chance to OHKO
252+ SpA Roserade Hidden Power Fire vs. 252 HP / 4 SpD Mega Scizor: 344-408 (100 - 118.6%) -- guaranteed OHKO
Now, her SAtk is clearly amazing, but it was already quite good, so what held her back in performing any sort of sweeper role? The answer there would be her mediocre speed. BUT, I have remedied that, and given her an outstanding
base 110, outspeeding the vast majority of the tier (fuck you Keldeo).
So, her offenses are unquestionably quite good, but what about her
defenses?
Well, I'm afraid to say, her Defense is garbage. Always has been, always will be. Her SPECIAL Defense, however, is quite nice, and should not be overlooked when finding an ideal set. Specially Defensive Roserade is always an option if you desire longevity over power, and she excels there as well:
252 SpA Choice Specs Keldeo Hidden Power Flying vs. 252 HP / 252+ SpD Roserade: 122-144 (37.6 - 44.4%) -- guaranteed 3HKO
252+ SpA Life Orb Protean Greninja Ice Beam vs. 252 HP / 252+ SpD Roserade: 221-265 (68.2 - 81.7%) -- guaranteed 2HKO
252 SpA Gengar Shadow Ball vs. 252 HP / 252+ SpD Roserade: 81-96 (25 - 29.6%) -- guaranteed 4HKO
252+ SpA Aegislash-Blade Shadow Ball vs. 252 HP / 252+ SpD Roserade: 99-117 (30.5 - 36.1%) -- 43.3% chance to 3HKO
Clearly, she likes taking non-SE hits better than the alternative, but with a combo of Synthesis + raw power, she'll do just fine.
So, now we've got all the numbers n' shit out of the way, let's talk flava.
I thought Serene Grace would be an excellent ability on Roserade. Sludge Bomb now has a 60% chance to poison, you can now add Shadow Ball to her movepool to abuse a 40% chance for a SDef drop, and it fits well aesthetically. Roserade is based off of a patron attending a masquerade ball, so naturally there'd be an air of grace about her, and it certainly seems more fitting than Technician.
I'll be honest, I'm quite looking forward to using Mega Roserade. An OU Grass-type Mega NOT named Mega Venusaur? Sign me right the fuck up.
