The skills and borrowed pages it took for Shirou to win: Shooting Caladbolg II like Archer, use Nine Lives Blade Works, summon an undead army wielding Gae Dearg, a Sword Spam that makes Gilgamesh's Gate of Babylon look tame, using Caliburn with Dragon Slaying Hero, invoking Curses Without End, channeling Lancelot with Arondight, invoking EMIYA's aria, and finally ending the fight with Saber's Excalibur. Saying that Guinevere was awed is an understatement.
Lancelot fighting Jord. The Knight of the Lake was slowly losing ground, when Shirou chose that moment to lend 'him' Arondight... Jord did not last long after that.
In part 2, Salvatori utterly humiliates Gilgamesh in battle, just like Lancelot Berserker did. He effortlessly destroys every Noble Phantasm Gilgamesh tries to attack him with using a single sword swing each.
