Boardgame development

(I know I made a post already but chickened out and deleted it haha)

I'm developing a boardgame pirate / armada themed and am wanting to get some ideas from your beautiful brains .

I know I should just think of it all by myself but I'm getting lost in my own head and need fresh minds .

what kind of card types could you use for environmental change i.e monsoon /monster or cards that effect ships i.e speed strength power.

any help would be appreciated thank you
