Tower on Fridays and the hometown on Sundays. He also faces the player in the Weekend Tournament, the K.C. Tower Tournament and is a potential round two opponent in the Sugoroku Tournament. When the message "Mako is not looking too good" appears on the screen, if the player talks to Mako, while their active Deck contains "Umi" and all its monsters are WATER-Attribute, he will challenge them to a special Match. In the Match, "Umi" is the default terrain and the player wins cards from the Water Collection, if they win.

Decks
Mako uses WATER Decks. His Decks usually rely on "Umi", which powers up his monsters, and can be used with "Tornado Wall", to prevent him taking Battle Damage, and "The Legendary Fisherman", who becomes protected from Spell Cards and battle. He also uses "A Legendary Ocean", as a substitute for "Umi", also allowing him to Summon Level 5 monsters, such as "The Legendary Fisherman", without Tribute.
