Hey, interesting team, I've got some suggestions to improve it.

Let's start with Bisharp. It's a great mon, and the set you have is ok, but the EVs need some changing. You're right not to invest in Speed, becauase Bisharp is pretty slow and already has STAB Sucker Punch, but investing in HP instead of Special Defense increases its overall bulk. Try using this set:

Bisharp (M) @ Leftovers
Trait: Defiant
EVs: 252 HP / 252 Atk / 4 Spd
Adamant Nature (+Atk, -SAtk)
- Substitute
- Swords Dance
- Sucker Punch
- Brick Break / Iron Head

This is basically the same as your set, but I changed the EVs, and put Substitute over Night Slash. With Substitute, you're safe from status. It also forces your opponent to attack, which works very well with Sucker Punch, eliminating the need for Night Slash. Brick Break is a cool move in the last slot, but try out Iron Head if you want a reliable STAB attack.

Scarf Porygon-Z is cool, but the moveset needs a little tweaking. Thunder is powerful and all, but its accuracy is unreliable, and it could miss at an important moment and cause you a game. I suggest changing it for Thunderbolt. Thunderbolt isn't as powerful, but it is definitely more reliable, and with Porygon-Z's fantastic Special Attack stat, you won't miss the extra power. Secondly, Hidden Power Ground isn't really hitting anything here, as there isn't really anything else that you can't hit with its other three moves. Becuase of this, I reccomend using Trick in the last slot. With Trick, you can cripple a wall like Snorlax that will switch in to tank your attacks. It also means that you will have freedom to switch attacks if you want, and will be able to recieve boosts from Togekiss, because you shouldn't be baton passing to a choiced Pokemon.

Cresselia is cool, but Attract is a really awful move. It's unreliable because you can't guarantee that every Pokemon will be male, and even when it takes effect, then it doesn't work all the time. I suggest replacing it with a move that will support your team, such as Lunar Dance. With Lunar Dance, you can kill off Cresselia once it's done its job, and fully revive something else. It's a wierd option, but try it out. It might just win you a game, and really, there isn't much else that you can use in the last slot, except maybe a coverage move or another status move.

I LOVE Slaking! Some people would tell you to change it, but you obviously want to use it, so there isn't much choice in that. Your set is a bit wierd though, try out this set, it's how Slaking is meant to be used:

Slaking (M) @ Choice Band
Trait: Truant
EVs: 4 HP / 252 Atk / 252 Spd
Adamant / Jolly Nature
- Return
- Earthquake
- Shadow Claw
- Fire Punch

Ok, let me explain how this thing works. When using Slaking, the best strategy is to switch in, hit incredibly hard, and then just switch out before you get tied down by Truant, and what better way to take advantage of Choice Band? Since you're going to be switching anyway, it doesn't matter in the slightest that you'll be locked into one move, and you'll get a massive Attack boost too. The moveset can be changed to your taste, but I just went for its most powerful moves, while maintaining great coverage. Return will just tear through anything that doesn't resist it, and Earthquake will obliterate anything that does. Shadow Claw is for Ghost-types that'll try to switch in, and Fire Punch is just for Bronzong. Basically, you need some decent predictions, and you'll easily take out some unprepared Pokemon. Watch out for Protect though, because anything with Protect will screw you over. Some people overlook Slaking's surprisingly fast base 100 Speed, and you can use a Jolly nature if you want to take full advantage of that.

Good luck with the team, I hope I helped!
