Startup-compliant exploitation of The Twinning, with Climactic Showdown to potentially further bolster the effectiveness of a single central server run.

And since it's easier to get The Twinning going if there's no ice in the way, might as well support Climactic Showdown with En Passant. Which basically means you wanna go Reina, given the Startup cardpool.
