Posting a rather weird but creative move I made:
Toxic Waste (status)
Poison / PP- 16 / Priority 0
"The user grants itself a boost in attack, special attack, and speed, but badly poisons itself as the cost.
Pokemon with Magic Guard cannot learn this move, and it's a nice little move that can make a Pokemon have a nice little sweep.
The only things I can realistically see getting this are Poison types that can't be badly poisoned in the first place.
But it would certainly be nice if Zangoose got this kind of thing...
Anyways, I've been toying around for a while with the Lake trio, who I guess are some of the most likely candidates for Fairy typing. To be fully honest, as they're supposed to represent the spirit world and apparently have the ability to separate their spirit from their body, I kinda think they should have gotten Ghost typing. Then I thought, if Mewtwo gets an alternate form, why not these guys? So, give standard Uxie, Mesprit, and Azelf Fairy typing, and give Spiritual Uxie, Mesprit, and Azelf Ghost/Psychic typing. Their stats would also be slightly rearranged.
Azelf - Standard: 70/125/70/125/70/115
Uxie - Standard: 75/75/130/75/130/95
Mesprit - Standard: 80/105/105/105/105/80
Just by nature of being the jack-of-all-trades, Mesprit is obviously the least useful. Uxie isn't too much better off, being a bulky wall with no recovery and bad typing. Azelf, on the other hand, gets away pretty okay, but could definitely use some more power. So, now we get to their Spiritual forms.
Azelf - Spiritual: 70/140/55/140/55/115
So Azelf trades the little bit of bulk he had in the first place for a respectable Attack and Sp. Atk stats that would easily give him his place in OU back. On the other hand his 75/55/55 bulk won't let him take any hits at all.
Mesprit - Spiritual: 60/115/115/115/115/60 Now, Mesprit is still the jack-off-all-trades, but that 60/115/115 bulk is very interesting, especially when backed by 115 Sp. Atk and Attack stats. 60 Speed lets him down, plus that Ghost/Psychic typing is terrible defensively.
Uxie - Spiritual: 80/60/150/60/150/80
With Uxie's new stat spread, he becomes very similar to his big brother Deoxys-D. However, he's still missing two crucial things that lead to Deoxys-D's (supposed) brokenness - Recover and Spikes. Without reliable recovery and with only one entry hazard, I doubt he'd be that broken. Also, that 60 Attack and Sp. Atk won't be hurting anything anytime soon.
I see Azelf-S as what Azelf was meant to be all along; a ridiculously powerful, ridiculously frail glass cannon. Something does seem wrong with that stat spread though. It's got the same BST as standard Azelf, it just seems stupidly more powerful. I dunno, maybe the fact that it would still be complete priority bait would help balance that out.
Mesprit-S moves away from being the worst halves of her two siblings to become a sort of bulky attacker / offensive support Pokemon, with good bulk and good attacking stats, but not particularly excelling anywhere and still being let down by that terrible Speed and typing.
Uxie becomes much more of a wall, taking more hits and setting up Screens and Rocks and whatnot. It can now also spinblock, and might even make a good Calm Mind sweeper.
So yeah, just some thoughts and stuff.
