Honestly your deck is bad. With second nature orb you losing access to such cards as razorshard and aggresor and its... Not cool. Deep one much worse than them in PvE. Living tower without root system is just "no comments" aswell. Ghostspears and spirit hunters in pve crap. You don't have breeding grounds in PvE deck it's also bad decision. You need much more healing, surge of life and regrowth is must have with nature orb. Razorleaf is also crap card without root sytem, if you want to play on defence missions, stonekin hammers will deal with it more than enough for missions that don't need specific decks. Your t1 is very overpushed, like you don't need mana wings and werebeasts in common mission, it's specific cards. You need Matter mastery, it's top tier Frost-Nature spell, just like Stone Shell. Wheel is good but you would like to take that t1 frost building that reduces cost of other building, forgot its name. I honestly don't like stone warriors in PvE, Deepfang is awesome thing. Battleship in non-vortex deck is crap, Giant Wyrm is crap (on non-specific maps, again), better take another Gemeye and again, you need regrowth. I don't like Grimvines also, it's much worse than Grinder. Example of my deck for any non specific PvE missions up to Expert and rPvE 9+

Actually it is a bug is from original game. Nowhere mentioned, that Scycatcher has siege, but when you looking on its damage, you see that its clearly has siege . I guess some good players already know this feature, but new players won't get it that easy. And yeah I can't understand, why some units has siege ability(Harvester, Sunderer, Tremor etc) on the card text and some not (Corsair, Scycatcher). I guess it won't be hard for you to add this text to the card? At least it will create some value for a new players. Like when I saw that Skycatcher has siege I started playing it in PvP 2vs2 and it was very fun.
