Aggro dragons! Oni Dragonsmith and Smokedancer become really efficient aggresive units when there's a dragon around, and Teething Whelp and Dread Hellkite are some good aggressive dragons. The welp can turn into a real threat if it keeps hitting (or in one turn if you play a Jekk's Knife on it) and the Hellkite can stop a unit from blocking so our team can attack easier. Unkindness is there to fuel our Devour or for a bunch of surprise damage if we get our Rally from the market.
