I shared this on Reddit and figured someone might find it useful here.
The SSD ship cards have square corners. The cards also appear to be made of the same material as the investigator cards or Ancient Old Ones cards from the Arkham Horror board games as opposed to the linen finish cardstock used in the other Armada ship and upgrade cards.
Square corners are much easier to ding and accidentally crumple. However this can be fixed with a corner rounder punch. If you want to get one, I recommend using a punch with a radius of 3mm (1/8”). These are the standard sized corner rounders used in playing cards such as Magic: The Gathering .
This is the corner rounder I use.
It was leftover from a previous project where I made custom upgrade cards for
X-Wing
. If you plan on proxying cards or creating custom cards i highly recommend a corner rounder punch. Makes your content seem much more professional
