Good thing it only took me like 7 times until i considered looking the guide from "ashe" up :S

Yeah, no need to deploy squads from left camp as the adjacent area lacks useful nodes (in this case, magnifier nodes) if you're going for the 3*. You can start playing around with 2-1-2 for extra coin farming once you achieve the 3 medals.

Also, don't deploy a team/helper at the bottom that is too fast, for it might just run past the 2 micro-pest nodes and not engage them before one of the teams at the top ring is able to hit the magnifier. The first team that "reveals" the random node of the ring usually tends to go down and you'll only be left with 1 more chance to hit the magnifier and engage the micro-pests if you didn't place enough squads near that ring.
