The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Ya.. The Procedure would be, Amumu Ult, Vladimir Ult, Nunu Ult, Fiddle Sticks Ult, and then Ryze with Ult+Spell Flux. I know the ults would have to be perfectly timed, but its basically a insta ace since Vlad's ult have the damage+ effect. GG!
