Mako's Combo is to bring out A Legendary Ocean, allowing him to summon The Legendary Fisherman without tribute, and Suijin with only 1 tribute. With the 200 ATK boost (And a possible boost from Star Boy), his monsters allow him a strong beatdown, with Raigeki Break/Magic Jammer/Imperial Order helping to keep the pressure. Since the attack is easy to sustain for Mako, he has time to acculamate the cards for Fortress Whale, and bring him out for some heavy beatdown.
