Mono White Deck cheating out a Black Card???
Hello,
I recently played a game against "fishrd1335." I was playing a deck I just made with Leyline of the Guildpact, as well as Amalia Benavides Aguirre and Wildgrowth Walker and he seemed to be playing some sort of mono white life gain deck.
I turned my head to check something in real life, only to find my Knight of Dusk's Shadow being targeted by a Murder!? After taking some time to analyze how he could have cast it, I came up empty. He only had one tapped plains and zero swamps. I checked his graveyard and exile and nothing was in there that could produce black mana. Additionally, he had no treasures to speak of.
While analyzing the situation, he began to BM me, which lowered my already low opinion of him, but that is a different story.
As you can tell by the images provided, he has a Murder in his graveyard (specifically from being casted, not from discarding) and no black source anywhere.
This seems like a bit of a problem, no?
