Morganna? Fiddlesticks? Mordekaiser? Amumu?
Or do you mean non ult abilities.
Ashe, Morgana, Anivia, Amumu, Karthus, Kennen, Kayle, Sona, Shen, Skarner...the list goes on.
Orianna wants a word with you.
blitz grab can also lose the team fight for them also.
I'd consider every ability in the game an ability that can win the game.
Anivia wall can be more devastating. Why pull one enemy when you can prevent roughly half from being in a team fight?
