Colonel_M, your few arguments aren't very good ones.
Shaymin sucks in OU lol. Too much Flying priority going against it, Scolipede is a common shitface to it, Mega Venusaur can at least tank a hit and threaten with Sludge Bomb, etc.
Wow, you've mentioned two Pokemon and a group consisting of about two other Pokemon as your only basis for rejecting it (at least, that you've posted). Most of these aren't even completely relevant anyway, Mega Pinsir and Talonflame can't switch in on Hidden Power Rock, if Scolipede isn't LO it can't OHKO Shaymin where Shaymin can OHKO back, if it Protect + Substitutes then it will eventually be beaten, and if it is LO, then at least it can't switch in, Mega Venusaur can't switch in lest it gets 2HKOed by Psychic, so these are situational answers at best.
I can repost my thoughts from the reservation thread later, but I'm too lazy to now.
Anyway, this is why I believe Shaymin should get an analysis:
- Seed Flare is a great reason on its own, giving Shaymin a powerful STAB move to spam, with a 40% chance of obtaining a Special Defense drop, meaning most bulky switch-ins that may try to come on Shaymin get forced out again by the fact that Shaymin can now OHKO them with a coverage move.
- Really good answer to Rotom-W, basically not minding anything it does.
- Decently powerful breaker midgame with its combination of Special Defense drops and great coverage.
- Most "would be" answer to it can't switch in at all on the appropriate coverage move, dying instantly. Prediction is a part of Pokemon, so don't say that this is a difficult feat.
- Great bulk, not Mega Venusaur levels but enough to tank neutral hits surprisingly well. Mega Venusaur isn't as fast, nor does it have Seed Flare, nor does it not give a shit about being burned by Rotom-W.
- Cures status instantly upon switch.
- Synthesis or Rest + Natural Cure for reliable recovery, with Shaymin's bulk it is difficult to wear down.
- No Mega slot :P
- Why would you use this? Ok, I want a Grass-type sweeper or wallbreaker that isn't frail, as most of my team can't break through Rotom-W, or my sweepers have trouble with Quagsire. Maybe one with nice coverage so it's checks can't switch in. One with enough power behind its STAB move to put a dent in things, while still possessing decent Speed and bulk.
I can talk a lot more about Shaymin, I can have people back me up, and also, it is finished, its viable, there shouldn't be any question.
