So, hey, Icaria's back! Which means--let's dust off one of our favorite archetypes--Icaria Blue! Now with better interaction, and more merchants! As this is a control deck, a lot of the interaction will be "season to taste". More heavy midrange in your pocket of the ladder? Trim some copies of defiance for more ice bolts or pristine lights. More aggro in your pocket of the meta? Trim the 1-of chains and a copy of Icaria possibly for a fourth knife or some copies of Rizahn.
Market I'm not quite certain of either. Sediti is a very real concern (though I've beaten him when he appeared in combrei shells, though Rakano might be a different story), so molot might be better as royal decree just to pick him off before things get out of hand.
In any case, nothing in the maindeck needs double primal, and the banner in the market allows you to round out your influence because you play 4 privilege main. Also not sure if palace or peak is the better pull from the market, but I think Icaria is better than either as a wincon in the maindeck.
Anyhow, this is just a tentative list, but feel free to use it as a jumping off point if you feel like picking up this archetype again. Enjoy :D
Edit 1: Rekenner complained about not enough primal. Fixed that issue. Privilege is a little worse now though.
