[six's monkey]

Moderator edit: This post was moved here since it's clearly discussing a house rule. House rules should not be discussed in threads where people are requesting actual answers to questions, not how people plan to play the card instead of using the officially intended way.

If I were running a non-tournament game (the only sort I expect to run), I would rule that a fireship with enhancers could broadside (for triple its current strength) and -then- be set alight to add eight to whatever the owner's combat total had been.
Broadside would be used, so it and fireship and attached enhancers would be headed for the discards.
