need help with my idea. I want to have a op at my store that is different and I was thinking of some kind of ruling that would force the player to have bombs in their list but couldn't think of a way to make it more flavor full than that. If any one has or knows of a format to help or any suggestions please share

The easiest answer is call the tournement "Bombing Run" and simply require one ship in each list have a bomb upgrade.

Alternatively, you could incentivize players by awarding additional MoV points for ships destroyed using bombs, i.e. ships destroyed through the direct effect of a bomb/mine are worth double when calculating Margin of Victory at the end of the match.

A more creative way would be to encourage Palp aces or imp aces

Then anyone who brought conners would have a field day
