This is an awesome idea. But let me say, the limit should go DOWN. I know, this will cause lots of complaining in people saying it should go up. But 2300 can fit 4 OUs and 2 UUs, (lowest of both sets) and the fun of this metagame is using Pokemon with low BST and a good role, even if you get some bad Pokemon. 2100 sound good?
Also, thanks for banning Ubers in this. xD
Now, here are some cool strategies.
Shedinja! This guy comes in at 236 BST.. my goodness thats low. Also, (bar rocks) he can switch in on anything not Super-Effective on it, Scout with Protect or Toxic, and switch out. He's a great filler for anti-sweepers.
Ditto! Yup, scarf him and revenge kill. Sounds good to me.
Nosepass! Yup, this guy comes in at 375 BST, with an Eviolite bringing him to 210 Def., and 135 Sp. Def. And can set up rocks, not bad.
Sunkern! .. No, I'm just kidding.
Abra! HOLY YES. 310 BST.. with a Speed of 95 and Sp. Attack of 105. Focus Sash the Abra.. nuff said.
Ambipom! Actually.. not bad. Might be pricey at 482 BST and for being pretty easily KO'd, but in all honesty, he could wreck havoc in this. Fake Out with Double Hit will do a bunch of damage with Technician.
Cresselia! This thing is costly as hell.. coming in at 600 BST. But if you use this thing, you'll wall everything in this metagame. Especially with that instant-recovery through Moonlight. 120 / 120 / 130 Defenses.. screw Arceus.
That's all I can come up with right now. But really, I'll be using Cresselia. The cost is high, but I still have 1700 BST to spend. That's only slightly more than about 200 a Pokemon, but using Nosepass or Shedinja will give me a party with 4-5 solid Pokemon, rocks, and a spinner, if I use Delibird too. xD
Awesome metagame!
