merfolk commander deck mtg Kumena, Tyrant of Orazca TRIBAL Magic Custom Good old fashioned Merfolk Tribal The 33 Best Merfolk Commanders

TCGPlayer is currently your best bet since you can look at a ton of card stores

While its the face card of the deck, I think Magus Lucea Kane is actually the stronger Commander

This flexible ability can be used both offensively and defensively, as when on your turn, it can prevent attacking Merfolk from being blocked by creatures of a given color

Any "as [this permanent] enters the battlefield" or "[this permanent] enters the battlefield with" abilities of the copied creature will also work
