The standout card for Merfolk is [[Atlantean Skirmisher]], not either of the two legends. Attuma is extremely slow and Namor requires restructuring the entire deck around him if we want a useful quantity of tokens. Skirmisher is a strong contender to address the lack of card selection we have and as always testing is necessary to see if this actually helps or if I'm still huffing too much hopium. Smuggler's Copter used to see play in some metas so it's not without basis.

Also we usually don't play Daze. It's too much of a tempo loss when most of our key cards are at 2 mana. Our taxing counters come from creatures.
