…Rook started your Turn 8 with 6 HP, took exactly 1 damage from Sparkshot, then was healed by Spirit of the Panda, as I noted at the start of Turn 9, returning him to 6 HP. That’s what I was referring to when I said I thought you’d forgotten something.
No, if I’d wanted to play anything more $1 wouldn’t have made a difference with what was in my hand.
