I coined that the first day of the expansion, spent the whole day messing with the Starhorn version on stream.
Speaking of that lets not forget my final draft from that day:

Ultra consistent deck with stupid amounts of draw, tiny chance of mechazor or Arkaki OTK, complete with some healing for stall.
Goal with almost perfect consistency being Q on 6, deci/spikes on seven, and then Heart/Deci/Spikes on eight. Even if you have one health and no cards left in deck despite taking damage up to four times during the combo it must resolve before heart breaks, meaning you survive with one health once it finishes. (Although it has crashed the client when the opponent also had a decimus on the field https://www.twitch.tv/videos/212979850?t=02h26m06s)
It was a scary consistent back to back decimus deck with no risk off dying to your own deci/spikes. Problem was 8 mana is awful slow for such a combo, even though you pretty much guarantee getting game with it it just remains a gimmick because Q kind of makes the rest of your deck pretty weak for such a late game plan.
Perhaps Alpha or Dream have a better idea just going for a more conventional approach and less dedicated combo, I just figure if you do that your probably just not quite as good as the usual version without Q, so I instead focused on really trying to highlight its power.
