Ascension: Storm of Souls – Assimilation Plant Promo

This promo was given out at a Game Day in 2012. At that time, it was both the highest honor-costing card, and the highest honor-yielding card in the Ascension card pool. Card text: "Your Mechana Heroes are Constructs instead. You may use their abilities once per turn. If this leaves play, put all of your Mechana Heroes in play into your discard pile."
