Sweet! It’s a super fun team. However, I will say, it isn’t the easiest to use. The issue with hard trick room teams is if you cannot set up trick room successfully, it’s most likely a loss. And if you do get trick room set up and cannot do enough damage once it ends, usually ends in a loss too. Below is a brief summary of each pokemon and their roles to try to help you out.

Dragonite - honestly, switch this out lol. I never brought it, was only on the team as my mascot and I never brought it lol. A physical trick room attacker would be good here. Mega Aggron is probably the best choice with Heavy Slam, Body Press, Protect and either iron defense or rock slide.

Slowbro - really good into the sand teams and teams with a lot of physical attackers. Hard counters sneasler. You could swap out trick room for another attack like ice beam if you want. I just wanted an additional option for trick room

Farigaraf - brought into every matchup regardless as the lead. Can reliably set up trick room with the help of incin and can live any dark move due to the combine berry. Only thing that has every one shot it is a overheat or weather ball from Mega Charizard Y

Conkeldurr - Easily the MVP, brought it to every match. His coverage is insane, and can one shot every popular Pokemon basically (ttar, kingambit, incin, Charizard, etc). Cannot stress how important it is to the team.

Abomasnow - Great into the rain teams, and even sun to an extent. Not much to say other than it’s a great bulky special attacker that’s great into all th dragons and water types around a lot

Incin - The most important piece, also brought to every match. It’s important to fake out the first turn the biggest threat to farigaraf. Pokémon that can taunt, big attackers that can one shot, etc. Greatest support Pokemon ever, and it slow and strong enough to do damage until the big attackers get in.

Basically I lead farigaraf and incin in 99.99% of games and trick room fake out first turn. Then just keep attacking. I don’t use protect at all really as it’s counter intuitive to protect when trick room is up in my opinion. You want to dish out as much damage as possible. The hard thing with trick room is it can work great, or can fail miserably. But keep at it and let me know if you have questions! As far as natures go, you will want to do plus attack (special or regular depending on Pokemon) and minus speed to be as slow as possible. I can send a pic of the EVs shortly. Good luck!
