Vidar is tricky. Issei states he confusing it was to deal with Vidar's arcobatic kicks. This was shown at how he found it hard to predict him. Every time he thought Vidar will use a high kick, it would turn into a mid or low kick. In short, Vidar had the upperhand in that exchange. I didn't bring up Euclid because I didn't see a point. Euclid is someone who can fight but doesn't have the battle mentality. He one of those who rely on pure talent. Also you missed the point regarding Strada. It wasn't about him nullifying a magic attack. It's the fact he was able to nullify it by pin pointing the weakness of the formula to cancel it out. Do you honestly think Issei could do that? Someone who has no understanding of complex formulas and equations revolving around Norse magic? Bringing up Azi and Loki as examples is ludicrous. Azi and Loki are beings who have way more knowledge and experience in using magic than Vali. If Vali tried something other than attack magic on them (masters of magic) then they could easily reverse it or cancel it out. Issei is someone who has no talent of using magic so it's safer to use it on him.

Because using Transfer and Penetrate on swords requires way less energy than Infinity Blaster. I didn't saying Infinity Blaster would render Issei motionleas but he would be exhuasted, meaning his movements woupd get slower and he would perform as good. For example, if Issei didn't use his Ascalons on Vidar after he used Infinity Blaster, do you think he would've won?

Again, you are missing the point. Crom has better battle senses than Issei so he had the means to counter. If Issei wasn't familiar with Kiba's fighting style, then do you see him even touching Kiba when they fought? Of course not. Kiba was easily evading all of attacks and countering him. Vali could do the same to Issei.
