I love MS-DOS and will probably vote for it. One of my favorite DPP teams used Metal Sound Zapdos and Screech Flygon together. I might revive that shit in UU now!
Anyway this Zapdos is about 90% theorymon, but I remember testing it in a team ages ago and it was okay, so I'll put it up to encourage a little more discussion even though it isn't as fleshed out as some other sets.
Zapdos @ Life Orb
4 HP / 252 SpA / 252 Spe Timid
- Rain Dance
- Hidden Power Water
- Roost / Heat Wave / Volt Switch
It's pretty straightforward - Rain Dance is Zapdos's best way of "boosting" its Special Attack by giving it a stronger STAB move and coverage move. HP Water destroys Rhyperior and unlike HP Grass it still messes up Gligar. Flygon takes a boosted neutral hit equivalent to a Hidden Power Flying. Nidoqueen is also not a big fan of a boosted Water move from the Pokemon she allegedly checks.
Damp Rock is an option if this is used on a rain team but the above set is a better "bulky rain supporter" than this, this set just kills shit.
Roost is for longevity, Heat Wave is used for a predicted Grass before Rain is set up but is otherwise a wasted move slot, and Volt Switch lets you pass up to three turns of Rain to something like Specs Kingdra or maybe a Tornadus.

we're all a little bit strange, don't worry about it
