I'm in a big rush and can't post scans this time, sorry. But I kinda need an answer before states tomorrow. Fortunately, the cards are commonly used. If I attack with Regigigas-EX's first attack after having played a PlusPower, but also have an Eviolite attached, and choose to do the extra 20, will I have the option not to inflict self-damage, or will it have to be inflicted? I think this is slightly different than Bolt Strike + PlusPower because if the self-damage is zero, you don't add to the self-damage with PlusPower. If I have an Eviolite attached, I would think I could choose to use that effect before PlusPower, setting the self-damage to 0, making PlusPower self damage not activate.
