Inspiring Clockroach

I haven't played since the game was first released and I used your list to update my old clockroach deck - I do have crown but nothing else.

Severin, the Mad Mage and Glasshopper seem to be a really nice way to ramp more reliably. They are campaign cards too.
I kept my Xenan Obelisks because of the mad mage. It's just a split threat - creature removal is really common but I don't see attachment removal very often.

Of the inspire cards, I only kept Xenan Lifespeaker and Amaran Armadillo as the others have a few problems, mainly double influence and/or high power costs for dubious rewards. Most of their effects are about countering or combat advantage. To me, clockroach is the deck that needs countering, not the other way round.

I actually dropped Dark Return and Excavate. I feel like that's a different deck without primal, incl @Asymat's suggestion. I mainly play clockroach for the Crown of Possibilities lulz. If I were to keep one, it'd be excavate as you can use it in lieu of a counter when you're camping with Annihilate in the opponent's turn.

Anyway, I think clockroach is the only double influence card in my modified version. It's going well but my rank is super low so I'll have to see what happens later.
