monkey d luffy one piece card game Starter Deck Purple/Black: D. anniversary celebrations OP07-091 Monkey D. Luffy (R)

Silvergil Adept is a great card that lacks enough other playable merfolk to be a cube mainstay, with AEther Vial cursecater, cryptologist and a few more merfolk the Adept could well see an A cube slot and give a huge boost to agro blue

Card Kingdom Card Kingdom is another alternative for singles

Despite this, the card sees a surprising amount of Commander play at all competitive levels, which could give this premium variant some value

There is a bit of deck building tech if you put in a number of historic lands, likely Legendary lands to mitigate getting stuck on lands

Or maybe its more serious than that
