Corpse explosion + Gruntled Patron.
I was playind as DK vs another DK. At one moment, he played the cards above. Infinite Patrons and corpses generation. At first I didn’t realize they would go infinite and thought we was trying to buff his Sire Denathrius. But then I watched his corpses go infinite and thought he wanted me to quit, but I’m stubborn and didn’t. To my surprise, his turn somehow ended with him with like 10 corpses and 3 Patrons on board. I had a big Denathrius on hand and he had low hp, so I could win. But I’m pretty sure he wanted to use this broken interaction to go infinite with his own Denathrius.
I don’t know if this is the right section to post, as i rarely use forums, but there you go.
