Trust me, I know about Ukraine.  My second wife was born in Ukraine and is a native Russian speaker.

The narrow border is enough to keep the edges of the faces completely uniform, thus making the cards indistinguishable from each other in a deck stack.  But you need to check with your manufacturer to insure that they can deal with a border that narrow, in terms of registration (making the back printing and the face printing match up as closely as possible) and making sufficiently accurate die cuts.  Some companies can do it, some find it a bit more of a challenge.

In general, the problem can be solved. Leaving a small edging in 2-3 mm

So will look like a joker and a jack, in the overall picture:

The connection between the cards is very unusual. But fascinating. Characters are full of emotions and experiences.

Interesting work, informative. They want to be considered.
