Bossing team to the right, Clearing team to the left
Attack the enemy below you using your clearing team and then defeat the enemy next to your bossing team
Move your clearing team to (2) and your bossing team to (1)
Attack the enemy below you using your bossing team then make your way to the boss for a 5-turn clear. Grabbing the present box below the boss will make it a 6-turn clear
You can make a five turn, three star and present box clear if you follow the mentioned starting points above, but don't have your bossing team attack the enemy near them.
Move your bossing team down to 1, attack the enemy below them. Move your clearing team to 2, then have the clearing team move back up and attack the target between the starts while having your bossing team proceed to the present box. This will allow you to attack the boss on turn 5.
