As a main roam/captain during the begining of the match I'll have my jungler take their fronts by the jungle shop treant. I'll usually make sure they're not trying to take the treant and if they do I'll usually try to steak it or have my jungler steal it. I also would have my laner to be in lane staying there and just farm, this way we can get more farms and be able to get items quicker. Early game I recommended you have scout traps by your tri bush, gold mine, and the lane bushes. During the early game you should take first and second wave with your jungler then go up and stay with your laner until mid game. You should have a fountain around 6 minutes into the match and still be able to have items like boots health items and armor. After you get your fountain you should start working on a cruicible for the team, espicially if they have a Phinn or Catherine. You should have your cruicible around 10 minutes into the match if you're building this way. I recommended not getting any damage items like stormcrown or offensive items until around 10 minutes into the match. During mid game should be rotating between your laner and jungler every 1 or 2 mintues. I would advise you build a contraption during mid game because for the reason that during the late game vision is key to sucess. During the late game you should keep your team together and not have anyone alone, always stick with your team and before you go into a bush, if you built contraption flare it and then go in that bush. During late game you never want to get ambushed and if one of your team members get ambushed or is killed during a team fight just retreat right away and regroup. Also always make sure to check kraken or have a scout trap by kraken to make sure the enemy team isn't taking kraken because if the enemy team gets kraken during late game they will have an advantage and the only way so they lose the advanatage is for your team to get an ace and take down kraken as fast as you can, but if you can't ace then you as a captain must try to distract them while your lane and jungler take down kraken. If you read this and do these things you should win most of your matches as a captain, sometimes matches can be unfair though so it doesn't always work.
