Just starting a compilation of effective strategies and combos for the Chaos Kingdoms. More input is certainly welcome.
Valkia the Bloody and Cloud of Flies (soften up the enemy while defending your quest zone)
Malketh the Changer and Warpstone Meteor Site (corrupt enemy units and cause Malketh to be more powerfull in any zone you choose.
The game seems to be all about units. So the bulk of your deck should effective low to moderate cost units. Support cards and heros should be limited to the combos you feel best work for you. So just because armories and cemetaries are nice to have doesn't mean they should be the first things in the deck. You should never have want for attacking units and sneaky ways to get them in to do damage.
