Forum:Heroic Challenger - Extra Sword

I just read that this card does not go well with Heroic Champion - Excalibur. so What they mean by that is that when Excalibur Doubles His Original Atk to 4000, Heroic Challenger - Extra Sword's effect does not apply anymore and it will stay at 4000 and not to 5000(using 1 Heroic Challenger - Extra Sword)?--121.54.23.2 (talk) 11:48, June 4, 2013 (UTC)
