Baron(Red Baron, Snoopy, you know)is the sweeper. Yes I know Fly is discouraged but I keep it anyway. Aerial Ace is stong ang and never misses. Close Combat handles most weaknesses and Brave Bird's powerful.
My other sweep.Grass knot cuz' it's essential. Flamethrower and Nasty Plot Are a good combo. Mach punch for a fast hit that may be essential.I know I can't increase it but still, useful.
Idon't own a Blissey yet so this is pre-planned. I maxed out Defense due to fighting type.It will use seismic toss for garenteed damage. Metronome for unothodox risks that may give me the edge. Softboiled to heal wounds and sing to immobilize.
What, he looks like a dirty robot to me. Wall-E is an Annoyer. Toxic sandstorms are his specialty. I put PP ups(dumb initials,I know.)on Toxic. Stone Edge criticals and dark pulse flinches. This one can probably use improvements so please comment.
I'm not an expert at analyzing teams, but here's a couple of thoughts:
1) Change up the moveset for Staraptor. You have 3 different offensive Flying attacks.. no good. Go with Return and/or U-Turn on that bird.
2) Choice Specs + Nasty Plot = bad idea. You keep on gaining stats, but won't be able to use your SpAtt. Either change the move or change the item (maybe Life Orb).
3) I'm not crazy about the Blissey moveset. Sing is very hit-or-miss and Metronome isn't very reliable. A BoltBeam combo may work, maybe TWave.
I think for a beginner, you've actually done pretty well for yourself. I like the nasty plot infernape - not many people use this strategy as infernape users all seem to spam close combat nowadays.
I like the toxic on tyranitar. Good call. But I would replace screech with a STAB move such as earthquake. With tyranitar's massive attack stats it is known to cause devastation. Not many would see dark pulse coming either, and it gives tyranitar the edge over high-defense steelies and such.
seismic toss for a blissey is good, but I would suggest a nnoying moves like toxic and thunderwave instead or attacking moves, as blissey is a very good tank and the toxic will drain the opponent during her (hopefully!) long stay, though is you're fighting a ghost type then I guess you do need an attack move other than fighting, so I'd stick with thunderbolt.
You might want to give your registeel an occa berry, just to counter the fire weakness (As iron defense does not raise sp.defense).
I like the hazing crobat, though I really don't think mean look is neccessary. I would go with Taunt as a safeguard, especially with the many darkrai spammers around.
Overall, I think this team has some quite unique movesets (better than a few I've seen!). Just a little tweaking perhaps :)
D: Don't replace teh blissey! Cloyster may have an exceptional defense, but with blissey's serene grace you can land a freeze or a paralyze with your current moveset. Plus her HP is an absolute bomb, with softboiled as a good restore move. Cloyster has about half her HP, and with no recovery moves I don't think it makes as good a tank. Though on the other hand, fewer people expect a cloyster to appear...
Tirael, Tyranitar is Rock/ Dark type. Where do you get STAB Earthquake from? O_o
Anyway, overall good team.
For the Ape, I'd go Close Combat > Mach Punch. Infernape is insanely fast as it is, so Close Combat is a much better option than Mach Punch.
Blissey... my Blissey uses this set:
Blissey@ Leftovers
{Natural Cure}
Bold nature
EVs: 252 HP/ 252 Defense/ 6 Sp. Defense
Seismic Toss
Softboiled
Aromatherapy
Thunder Wave
SToss for consistant damage. Softboiled for recovery. Aromatherapy heals any status problems your team-mates may get afflicted with, which is so helpful, every team should be forced to have one. Thunder Wave cripples opponent's sweepers that like to switch-in on Blissey. Watch out for Electivire switch-ins.
Tyranitar looks bad, just going to say. I'd go with
Tyranitar@ Choice Band
{Sandstream}
Adamant nature
EVs: 252 Attack/ 178 HP/ 80 Speed
Stone Edge
Crunch
Pursuit
Aqua Tail
Stone Edge gets STAB, as does Crunch. Pursuit is insanely powerful with Choice Band equipped when the foe switches out. Aqua Tail hits Hippowdon, other bulky Ground types, and Fire types.
Overall, it looks like an ok team. Why not postg it in Team Building boards to get more people to help?
