Tyrion's Enforcers: "If you have fewer cards in hand than each opponent, Tyrion's Enforcers can attack or defend military challenges while knelt."
Frozen Moat: "Challenges: Kneel Frozen Moat to choose 1 attacking character. Until the end of the challenge, treat that character as if its printed text box were blank."
If I declare an already kneeling Tyrion's Enforcers (TE) as an attacker during a military challenge, and my opponent blanks him with Frozen Moat in the Player Action Window after I declare and kneel attackers, is there a memory of TE having already knelt when being declared for a challenge, so that they become ineligble to attack and are thus removed, or does Frozen Moat do nothing, as they were eligible for attack when I declared them.
This came up yesterday, and we collectively ruled that Frozen Moat does nothing in this case, but I wanted to make sure we did the right thing.
