ok this might not be the slowest team out there but I figure that These are all heavy hitters and my slow team. I wanted to off the bat get as many pokemon with limited to no weaknesses and make a team. Here it is

As much as I love Bisharp, and trust me I do till death do me the Power Rangers apart, as well as Kamen Rider, Fortress might be a good niche in this team. As I was informed, others might switch alot to waste my Trick Room timing, so why not throw up Stealth Rocks and Spikes first. I am planning on this as a lead for that. Rapid Spin will make my switches much easier to do while the always great Gyro Ball will hit hard. I did 252 in sp def so that he can take the special hits too but if this is not good, please do tell me, I am a Fortress Virgin.

He was not my first choice for my team originally, I was going to go with good ole reliable Snorlax, everybody love Snorlax, In Soviet-Russia Snorlax love you. But I noticed one thing, except Bisharp, my team was slow as dirt, I mean Excavalier is the third slowest pokemon in game despite his other delicious stats. So I figured, well if I am going slow team get best trick roomer I could think of then screw Dusknoir, I will go new school. So here is Reuniclus. I picked Trick room because my team was slow as dirt and now they are fast. Focus Blast is a very powerful move that will hit those darn dark types that want to switch in and ruin my fun. Recover just makes this guy harder to kill and lets him do more then one Trick Room. the final move is a simple Stab move Psychic. When nothing else fits why not get a good psychic off right? Leftovers is chosen to make him a little bugger. I just kept thinking of the move lineups and had to do something about it.

My third pokemon is the ever lasting knight in my mind. Only problem I had so far was a sun boosted fire blast killing her, though I wonder why they took the time to set up the sun first. Her defenses are great, and her attack score is amazing, infact if she had half the speed of Scizor she would be busted in all ways. Megahorn provides pure killing power, able to leave a dent in those that resist it. Iron Head is a great secondary Stab and in Trick Room the flinch becomes an issue to deal with. Pursuit is there because I know some will run from her in a switch. Subsitute just makes her even more ungodly to kill and makes her have a way to deal with status. I gave her leftovers to go with the Subsitute so I can happily make more of these unyeilding knight subs.

Ok, first I was like [Lets do Spiritomb, he has no weaknesses blah blah blah] then I was like [Porygon2 has one weakness, he will so be perfect, thank you ColorAndLight, still say thansk for the suggestion] Now I am like ok I am trying out Fortress and heck no am I giving up my Knight, so why not do the pokemon that starts off on a birthday cake and makes his way to the ceiling. Yes, brilliant it has Flash Fire, making when I bring him in to save my steel bugs, he will be stronger and they might switch. Then I went but they might switch in with a rock or water or ground type that is not part steel, so I answered ok whining voice I will do Energy Ball to handle them. But then I said But they could also go Dark on you so I answered again Let there be Focus Blast. To finish out the move lineup, I am torn between Heavy hitting Fire Blast or good ole reliable Shadow Ball. Leftovers just make him a pain in the but and Trick Room on him makes him and the team brutal.

This is the son of the forth gen Swampert I had, similiar move pool and everything. Hammer Arm is a double killer move for him, not only a power house fighting move, but also lowers his speed that if I am correct means he gets a speed boost in Trick Room. Water Fall and Earthquake are great move non the less and stabbed on this monster of the deep, making him a powerhouse killer. Avalanche is the last move but not any less deadly. When Trick Room is not active it has a high chance to have base power of 120 and is a great check to all the dragons in OU. Muscle Band does not lock him in a single move while Choice Band gives him the power boost to a single move to make him so much more of a threat.

My last pokemon and the one that inspired this team in the first place. Having no weaknesses is great, I always joked to my friends that make a levitating electric type would be broke and funny thing is they said if they did that it would have a second type. Geuss the second type was wrong. Charge Beam makes his average special attack into a killer power level and has stab to boot. Acid Spray is similiar to Charge beam, making his average Sp Atk feel much more powerful. Flamethrower lets me handle some of those new Ground Steel a gigmurs easier then before. Volt Change and Thunderbolt are last move choices because they are great killer moves with stab. Discharge is there incase I wish to Tag Team my Swampert with Eelektross, and is a powerful move on it's own, even without the paralyse chance. Electric Gem and Poison Gem can be switched since the first actual attack would be either Charge Beam or Acid Spray.
If you have a question why I put something on any of these pokemon please ask I will try to answer and please tell me advise so like all teams it can improve
