Haven't seen this in a while, maybe I just haven't run into it. I miss Heretic Canon as a game turning weapon, I really like Valiant Guardian, and prefer him over Kiln Titan, but I figured both would be fun. Play sentinels, draw cards, hold off your opponent until you set up and start bashing in with Valiant or whoever. A few relics to power Coretapper, and a pinch of removal.
Market holds Worldpyre for cheating out sentinels, or Stirring to reanimate sentinels. Suggestions are welcome.
