I was about to post for the EXACT same thing. Happened to me and I lost a game because of it, I was so MAD. I was about to copy Thalia with 2 ratadrobiks against a control deck, but arena wouldn’t let me. What happened? Board wipe where had I got those extra thalias wouldn’t have been able to be played. I had the opponent down to 5.
Had a secluded courtyard with humans selected. Why can’t I make red mana to activate an ability of my HUMAN creature.
