Another Serious merge project team

Even though I haven't fully merged all of my water and earth-based teams, I do have enough feathers to get them up there once I get more copies. But I also want to make at least 1 more merged team comp, which means I will go back to HM farming. As for what kind of team I'll make, since my water team is mixed and my earth team are fliers, I figured I'd do either a cavalry team, infantry team, or a team with Eir; but I'll let you guys decide which path I'll take.
