I'm viewing this as a battle including Megas, mainly because it would make it more different from the OG battle royale. Anyways, unfortunately for me, Swampert dies horribly here, as he gets blitzed by both Sceptile and Blaziken, as well as Sceptile not only being able to easily exploit his quadrupled weakness to grass type moves, but he also has added STAB, which further digs Swampert's grave.

Now it goes down to Blaziken VS Sceptile. I should mention that only Mega Blaziken has a useful ability in this matchup, and Speed Boost certainly should be able to help him match and surpass Sceppy's speed over time. While Sceptile no longer is weak to fire type moves, Blaziken still has Brave Bird, which should be enough to beat Sceptile. So I think the winner is Blaziken.
