Forum:Cyber shadow gardna effect works in the battle phase?

If I have played my "Cyber shadow Gardna" in attack mode in OP main phase and he then choose to attack it with a monster like "Soul of Purity and Light" or a random monster but then also use cards like against "Pyramid Energy" or "Rising Energy" will the atk of my "Cyber shadow Gardna" be changed again to match the new atk or will it be the atk of the op monsters when it declared the attack? 87.73.72.11 (talk) 13:17, December 5, 2011 (UTC)
