Precon dilemma for a high-stakes tournament (Mox Diamond prize!)

A LGS near my hometown is opening a larger venue and the owner is hosting an inaugural tournament next Saturday. It’s a precon-only event, and the prize is a Mox Diamond!

I’m not used to playing with precons and I only own three at the moment:

- Endless Punishment:

- Eternal might:

What you would choose for a tournament and why?

Thank you in advance for your explanations!
