i need help im building a team and im missing a pokemon
my team
Charizard
-Fly Air Slash (Fly is a physical move, and is a 2-turn move which gives a free turn for the opponent to set up. Go with Air Slash if you need a flying move)
-Overheat Dragon Pulse (Fire Blast already takes care of the job, go with Dragon Pulse for type coverage)
-sunny day Focus Blast (Focus Blast is another great type coverage, although the accuracy's a little shaky, besides, you really don't get much out of Charizard using Sunny Day except for Fire Blast)
Fire blast
(Comment: Charizard is a great pokemon overall, but it is cursed with a 4x Rock weakness - which means you will get 50% off once Stealth Rock gets you.)
Venasaur
-Toxic / Sleeping Powder / Substitute (okay move with Leech Seed; may replace with Sleeping Powder or Substitute)
-Sludge Bomb (horrible Coverage, but better than nothing)
-Energy Ball (Main Attack)
-Power Whip Leech Seed (Special Attacks are better way to go for Venusaur, use Leech Seed)
(Comment: Venusaur is not that great in my opinion as in stats or typing, but if you want a Leech Seed staller, go for it.)
Gliscor
-Aerial Ace
-Stone Edge
-Earthquake
-U-turn
(Comment: Looks good, and Gliscor is a great physical wall with a respectable Attack. Just watch out for ice attacks.)
Floatzel
-Surf Waterfall (Why use surf when you've got a physical Waterfall to work with a 20% flinch chance and great speed from Floatzel? :P)
-Crunch (Good)
-Iron tail Ice Fang (Iron Tail has poor accuracy and Steel isn't the best offensive types around - go with Ice Fang for great coverage)
-Rain dance / Return / Brick Break (Actually works with Floatzel + Swift Swim, but if you're using Charizard as main, don't use it as it will weaken Fire Blast; use Return or Brick Break.)
(Comment: Floatzel's a pokemon with respectable attack and great speed. However, it's pretty fragile, so don't expect it to sweep a team.)
Heracross(I'm changing for lucario)
-Brick Break Stone Edge (Why use 2 fighting moves when you've got a 120BP Close Combat and a great rock attack called Stone Edge? :P Stone Edge saves you from Flying types who will eat Heracross for lunch.)
-Close Combat (Good)
-Megahorn (Good)
-Bulk Up / Night Slash (Either works, but I prefer Night Slash, for hitting Ghosts and Psychics.)
(Comment: Heracross is one of the most scariest pokemons in OU tier, so why not use it? Lucario is also great, and has about the similar reputation as it, except it has hight Special Attack at the cost of lower Attack.)
I'm thinking normal, psychic* or ghost maybe
oh and i need a better move set for charizard
and for floatzel
