This card is rediculous strong. My friend tested for the first time in his Leo deck in our Guardian of the Abyss first scenario and he managed to soak all the damage from monsters and treacheries. With the Wish Eater token cancel, he could pull all the attacks successfully, even when the abyss level became 5 or 6. We played with the Forgotter Age punishing chaos bag (we are at the last scenario in this campaign) and we won really hard. This card is essential to all tankie characters and IMO is a game changer. Also, with the swarming mechanic in Dream Eater, Empty Vessel becomes more strong, even one of the greatest cards for Guardias who have low sanity.
