I don't see a win condition for Silver against Trunks. Dragon Ball characters get thrown through mountains on a regular basis, you're not putting one down with blunt force trauma unless you really, really bring the blunt force. Throwing everyday objects at one with telekinesis? No and Trunks has a sword, he's just going to cut them.

Grabbing Trunks and tossing him around? Trunks can fly. See also killing a Saiyan with blunt force above.

Yes, Silver can go super and be invulnerable for a while. But Trunks is a pragmatic fighter, he can take it for the duration.

So.... how does Silver win even once if everything comes up Silver?
