Two moves I love right now are the Electric Chair Driver/One-Winged Angel/Ulster Plantation and the Stormbreaker.
The One-Winged Angel just always looks nasty and a definite "Yep, they're done," move and no wonder 90% of people in e-feds are trying to use it.
As for the other, the Stormbreaker is an example of a move that, sure, may not work in a "regular fight," but it is just flashy enough to be amazing, especially when Ospreay has shown he can hit it on a larger person.
