I assume those are Focus Sash Variants of Deoxys since if it carries Life Orb, there is no way Blissey is going to survive a Superpower. That is why I think Focus Sash variants are pretty dumb (only the ones with Stealth Rock. I can see use for them with S-Power/Psych Boost/X-Speed/Hp Fire since it will be able to easily kill almost all the steels switching in and since people rely on priority to kill, they're going to cry when they lose one because it survives and kills back and they've pretty much lost their only hope. Stealth Rock is a waste of potential on Deoxys).
Go Mew power!
How are you suriving Psycho Boost considering unless you''re 4X resist/immune, everything gets 2 hit koed by it. Shadow Ball would make Mew cry but otherwise I could see defensive Mew nuking it with Light Screen. I bet that is what is being run (because Mew is a sexy strangely underrated but shouldn't be because it is a monster like the other ubers yet not being discussed).
Actually, I'm having some respect for (good, none of that Stealth Rock suicide Deoxys A crap which is stupid on Deoxys) Focus Sash since while it does lose some major power with Life Orb, it will reliably kill steels like Jirachi, Metagross, Scizor, Brongzong, etc before it goes down and if people rely on those, there's trouble. Scizor is roasted and Jirachi/Brongzong (maybe, although without Life Orb it won't 2 hit ko anymore without sun or other damage)/Metagross (except Special defensive Metagross) will be 2 hit koed and if hit on the switch, they'll attempt to kill Deoxys and die. Bronzong won't even get a chance because of it's speed and neither will non-Choice Scarf Jirachi. Metagross can attempt to Bullet Punch but Focus Sash will save Deoxys. Good predicition is obviously still required to hit those (obviously coming) steels but the good news is that now it doesn't die to Choice Scarf Darkrai/Shaymin-S and koes them as well.
Yeah it might be sash one.
About mew. Well he psycho boost 2hko. Right.... so what ? i roost of the damage while he lost SpA making non Shadow ball deo-A a joke. Then i can burn him with Will o wisp making bliss a reliable switch in unlike before. In fact factoring lefties, Deo A has only small chance to 2 HKO with psycho boost. Psycho boost isnt as godly as everyone think off. You migh be blinded by his 180 attacking stats but deoxys-A attacks are in fact not as powerful as you might think it might do. I fear Specs Timid Hydro Pump from Kingdra in the rain more that Deoxys-A in a whole to be honest after i experience how pathetic Deoxys-A compared to what happen when i deal with him.
First is because Kingdra is faster. Second is because Water is superb typing (both are resisted by Nattrei anyway for posterity sake)
Remember mew is UBER LAST GEN and PSYCHIC ATTACK IS CRAP IN UBER LAST GEN making Psycho boost mediocre against fellow uber resistor. Result : NEVER OVERHYPE PSYCHO BOOST...EVER.
Psycho boost is only a draco meteor with worse typing and 180 SpA means he does 15 % more against same pokemon with same investment and item when compared with rayquaza
Against mew even latios specs DM fail to 2HKO in full health assuming mew roosting. Then he can Roost the second time and LS away making next ecounter fairly easier.
Homever should be noted shadow ball variants make me losing the power of stall mew. Stall mew is practicaly my MVP in most situation seeing how well he deal with this metagame.(yeah all this mew talking is about defensive mew which work really well in practicaly every kind of team)
Why stall mew ? BP mew is broken ? what a joke. BP mew is pathetic this gen (dunno in last gen) especialy in OU but surprisingly not in Uber, In uber he has the necesarry suporter and necesary
sweeper to pass against (Gr OU don should be named Gr UBER don after all and the sweeper choice range from That beast, Rayquaza, Dialga, and giratina and many more ).
In OU this gen, theres dragon Tail which is more common and Doryuzuu is more potent seeing the weather summoner isnt as broken as in Uber although they are still good(compare Politoed against Kyogre and Ninetales against GrUBERdon) which play crucial part in most cases.
As shrang said before, Ou dont have Set up = win pokemon like in ubers like the aforementioned Gruberdon making passing to sweeper not as rewarding in ubers especialy if the receiver is not named Metagross who cant OHKO Nattrei easilly. Weather summoner in uber play a part that when you see that you cant pass easily you use them to do immedite threat after switch in (not to mention kyogre is an adept cleaner for BP mew team and Gruberdon is a great, nearly the best recipient)
Stall mew homever is only stopped by miss, faster taunt, faster Sub, Robushin, MH, Taunting Magic mirror switch in, and fire type that can 2HKO without losing to roost stall and even then mew's (ussualy) light screen moveslot can be tweaked with other move of your choice to beat its counter of your choice. It fit in the metagame for making nattrei from dominating wall into set up bait, laughing at foretress, beat many Ttar variants and with AT blissey in waiting(yeah use bliss seeing how sandstorm is quite dominant), Magic mirror user can be poisoned by toxic safetly only waiting for its demise. Oh Did i mention that Chansey lose to Stall mew(even more than Bliss) ? Ths leave me wonder why stall mew isnt discussed instead of BP and why many dont use it(especialy if they say power creep the reason)
