He said he was sliding; however, sliding visual lag always show you sliding away from the monster, this guy is sliding towards it. Also, his lugias' flame is swinging down which tells me he was further away when he started to attack. People have asked him to make a movie and re-create the scene, but he have ignored that option and posted irrelevant pics.
Sliding visual lag does not show you attacking a monster from a further distance. It only show you running further away, which cause the monster to miss his attacks and it's the purpose of sliding.
P.S. Payback is a b1tch isn't it? It's your turn.
