I attacked with Earthshaker Dreadmaw, intending to use Dreadmaw's Ire to kill an artifact. It never gave me an opportunity to use the trick, thus losing me the last game of my draft. Could I get some sort of refund?
I had the same sort of issue. I played Dreadmaw's Ire. Oppenent has 2 artifacts. After combat damage, the card didn't function.

Your opponent controls Sandswirl Wanderglyph. It says you can’t cast spells if you attacked them this turn.
