Forum:Cup of Ace vs. Protector of the Sanctuary

Protector of the Sanctuary prevents you from activating cards that would cause the opponent to draw, if you control it on the field. Cup of Ace doesn't determine who gets to draw by its effect, until the coin is flipped during its resolution. Normally, if it's unknown if a card would perform a certain action until it resolves, any card that would specifically prevent that action can't affect it (like trying to chain Barrel Behind the Door to Abare Ushioni). So, would Protector of the Sanctuary prevent me from activating Cup of Ace altogether, or would it just merely stop the opponent from drawing, if I get the wrong result? 66.228.109.2 16:13, March 29, 2010 (UTC)
