I looked at Choice Scarf Mewtwo, which is
both a lead and a revenge-killer, and came up with a similar idea for Deoxys-S:
@Lum Berry
252SpA/6SpD/252Spe
Timid nature
~Psycho Boost
~Taunt
~Stealth Rock
~Ice Beam
Psycho Boost is used for the likes of Choce Scarf Heracross (which are outrun even if Jolly), which can really save me a match in an already Bug-type weak tier; Ice Beam is obligitory, as Deoxys-S outruns even Jolly Scarf Garchomp; Taunt is both against other leads and Wobbuffet, which will dry out of Mirror Coats due to Deoxys-S's Pressure; SRs are obligitory, as I run this on offensive teams.
Now, would this work?
Coldeye, we've told you time and time again.
PSYCHIC ATTACKS SUCK IN UBERS. HOW MANY TIMES DO WE HAVE TO TELL YOU THIS BEFORE IT GETS THROUGH THAT THICK SKULL OF YOURS. Choice Scarf Heracross is uncommon compared to other ubers.
Opinion? Also, should LO Gengar use Destiny Bond? Should Mewtwo ever use Psychic? Some of you said never, others said it can work, so I'm a bit confused...
Also, what move is generally better for Mewtwo, Thunder or Shadow Ball?
It might work as a gimmick but the additional coverage would be more helpful from the attacking move that you're missing out. See above for my opinion (and several others') on Psychic type moves.
Depending on your team, either Thunder or Shadow Ball would work. However, Thunder is generally the better option for hitting Kyogre.
For the analysis thread, can I just post a new set I tried a few and that worked or I have to follow a long list list of rules to have the right to post it? Can I PM moderators to have their approval or anything? The set works really really really well and I am willing to write an analysis about it. How does it work?
As long as you follow the proper HTMLizing (see past analyses), have the proper prose, and follow the correct formatting, you're free to post it in the appropriate subforum of C&C.
