I went from one win from diamond 1 to 0 points in diamond 3 losing to dino nests and stormhalt plating. So this deck is purely designed to beat those two things. Play blocker dorks and then sweeper them. If they try to hold anything back then make them discard their hand. If they don't pressure you then steal their plating with the staff or kill them with magniventris.
These games are super grindy and no fun for anyone.
Went 13-7 in my last few games to masters.
Also lost horribly to Applechip's and Liontozion's different versions of Feln heroes. So shoutouts to that and hope you don't face it.
