I really like the idea of these Dunland guys, however with the Dunland Chief hero it's entirely possible that you may not have to discard a card for 2-3 turns in some cases, so he'll be under performing a little during these instances? Maybe give him a Refresh action ability like Erestors?
The Dunland allies obviously facilitate getting cards into the discard pile but you're making them very dependent on the setup of the other heroes (2 of the same sphere) with the Chief and drawing into the right Dunland ally on the first turn?
Also there's a little typo in the Chief's card (tompost). Great reversal of the card hate theme though
