If by the Algol move you mean his "headbutt from full crouch", the move is actually iFC 8B (and BE counterpart). It really isn't a glitch, it's a buff that he was given in the 1.02 patch. It read: "While crouching 8B (Alruccaba Vega): Increased damage (20,30→40,20). Increased chance of clean hit possibility. Reduced hold time when executing from standing." This is why it looks like he is glitching, but is really using his buff.
