This is my first Gen V team so any suggestions would be highly appreciated! I haven't been able to do any wifi battles yet but I have versed other teams before so I have tested out this team.
Crustle @ Lum Berry
Ability: Sturdy
EVs: 4 HP, 252 Atk, 252 Def
Nature: Adamant
-Stealth Rock
-Spikes
-Stone Edge
-X-Scissor
At first I wasn't to sure how helpful this little crab would be but once I used him he proved himself worthy to me. He is a pro at getting stealth rocks up and sometimes as a bonus he can get a few layers of spikes up. If someone taunts me I simply use Stone Edge and X-Scissor to take them out (many taunt users seem to be weak against rock and bug type moves). Gave him an Adamant nature instead of Impish because the Sturdy ability makes sure I survive one hit anyway. A lot of people have underestimated how hard this guy can hit.
Cofagrigus @ Leftovers
Ability: Mummy
Evs: 252 HP, 136 Def, 120 SDef
Nature: Bold
-Shadow Ball
-Will-O-Wisp
-Haze
-Rest
The rapid spinner blocker. His move pool may really stink but I like him. No one can set up on him because he has haze and stops many physical attackers. Rest isn't the best recovery move ever but his high defensives help and people can't toxic stall me. Rapid spinners may be uncommon these days but my team relies on spikes and stealth rock a lot. Not to mention that Cofagrigus pairs very well with my Blissey too!
Starmie @ Leftovers
Ability: Natural Cure
EVs: 4 HP, 252 SAtk, 252 Spe
Nature: Timid
-Surf
-Thunderbolt
-Rapid Spin
-Recover
Oh Starmie, how you continue to amaze me with all your awesomeness. Although my team doesn't really have a stealth rock weakness I do a lot of swithing in my group and Blissey doesn't like toxic spikes. Starmie's high speed and decent special attack even allows it sweep sometimes. Too bad there wasn't any room for Ice beam on this set. Recover is too useful to get rid of.
Scizor @ Choice Band
Ability: Technician
EVs: 4 HP, 252 Atk, 252 Spe
Nature: Adamant
-U-turn
-Bullet Punch
-Superpower
-Pursuit
Yes that is right. It's your good old Choice Banded Scizor. I'm in love with priority moves and Scizor is good at just that. He is good for my team because he can finish teams up with bullet punch that are weakened by spikes and stealth rock. Also many of Scizor major counters are weak to stealth rock and since my group is so focused on that why not put a Scizor in my team?
Skarmory @ Leftovers
Ability: Sturdy
EVs: 252 HP, 252 Def, 4 SDef
Nature: Impish
-Drill Peck (probaly going to change this to Brave Bird)
-Spikes
-Whirlwind
-Roost
Skarmory fits this team so well. Gets up the layers of Spikes that Crustle wasn't able to get up then I whirlwind away to my heart's desire. Pretty straight foward. He always pairs up well with Blissey (pretty sure all of you already knew that though).
Blissey @ Leftovers
Ability: Natural Cure
EVs: 252 HP, 252 Def, 4 SDef
Nature: Bold
-Seismic Toss
-Ice beam
-Toxic
-Softboiled
Many people hate me for using Blissey but she reminds me so much of Jigglypuff I had to use her. Besides I wanted a good special wall and here you go. I chose Blissey over Chansey for three reasons: 1. I don't like the idea of people setting up on me 2. Because of Sandstorm (and Hail) I like her to have Leftovers and 3. Blissey just looks way better than Chansey anyway. This moveset is a little different from most Blissey but as I said before I don't like to be set up on so I give her Seismic Toss and Ice Beam. Softboiled is for healing and Toxic drains people health slowy away.
Things I like about my team:
Because I have alot of walls on my team my opponent has to switch their pokemon a lot for a better match up. Thats where spikes and stealth rock come in. Scizor's U-turn, Blissey's Toxic and Seismic Tosses, Cofagrigus's Will-O-Wisp, etc. all helps weaken my opponent's pokemon. When the moment is right I sweep with my Starmie or my beloved Scizor.
Things I don't like about my team:
Here is a list:
-No fire moves (Forretress likes to set up Spikes against my Cofagrious)
-No ground moves (Earthquake is such an awesome move and no body in my group has it)
-And the biggest issue is no pokemon in my group can change the weather
This team has an extra hard time against sunny day teams because the sun decreases the power of Starmie's Surf and I have 2 fire weakness in my group. Once the sun is up there is no way for me to change it and it kinda sucks.
This group is new so there are probally more flaws in it so if any of you have any suggestions please let me know!
