PIRATES
1. If you spot a potential plunder but that fleet is reaching port in maybe 1 minute(for the pirates who dont do 6/20) this would help alot.
2. When you are plundering a player and the scavengers arrive, simply delay the time and get more......time.
TRADER
1. If you are under attack your guild mates can use this card to extend your port arrival time limit. Thus, saving you thousands or even millions.
2. If you are trading and your fleets are racking up danger(new players mostly) you can use this card to extend your routes over the hour limit.
This card should be uncommon or common not many persons are going to like this being a rare card, right?
