I'd say: - Stick with 50card decks. Don't throw in more than 60cards. - Try to avoid throwing in many single copies of cards. Usually less variety of cards makes standard draw more reliable. - 3x Contested Village is must-have. - Warpstone Excavation and Innovation are usefull in 80% of decks. Those are great cards. Don't underestimate them when building a deck. - Try not to build deck with less than (at least) 9-12 supports that are capable of providing power to kingdom or mission. Heavily unit-focused decks won't work well since they are vulnerable to mass removal. (Troll Vomit, Master rune of spite, Flames of Phoenix, etc etc.)

Wichtel said: Using Moon Staff of Lileath on your opponent is a great idea. Not really, since it will work only on opponents playing HE decks. (Attach to target HE unit) Both Dragon Armour and Moon Staff are relatively weak cards. Sadly, all purely HE cards are weak (underpowered even) compared to other races. (I mean - compare relics from warpstone chronicles. HE one looks just silly when opposing to Orc one. Or Empire. Or Dwarf. Or even Chaos one. Same with Epic spells - Morvael's Legacy is just variation of Reclaiming the Fallen. And it's not even really much better than the dwarf non-epic 5r cost tactic.
