Well don't worry about the Tyrogue as Rinnia and others should be able to KO it. I plan to have Windmill come join you on the tree(if it can make it from where it is) since its Peck attack is SE on the Trees. If Glacier sprints, he could join you up there too with Powder Snow even affecting anything on the other side of the tree(since its a line shot). Granted in Glacier's case, he might be better off moving to D4 to heal while helping to cover our flank. I'm just in no position to lend a hand to anyone or risk being KO'd. What people ought to try and do is utilize our two flyers(Hit and Windmill) to flank the enemy via the cliff and to try and keep them occupied from attacking our people hitting the trees. Even Rinnia can make it up there through its Teleport ability.
