Can in the name of the lord somebody explain to me, what's the digital part of this card that wouldn't be "reasonably" or "logistically" be doable in paper?
It's perfectly reasonable. It simply means they are trying out new things as well. The digital environments seems like a good place to try out new things regardless whether they can be done on paper or not. "Wins" seems to imply they creature you control did not die due to state based actions immediately following the fight while the other creature did. I bet we'll see it in paper.
The reason for this one probably is more subtle than the others: The fight doesn't kill the creature, state based effects kill the creature only after the spell is done resolving. If you wanted this to work in paper, it would have to spell that out in one of several awkward ways instead of the game engine just recognizing it. (Also doesn't say if "wins" includes your creature surviving or not. Is both creatures dying a "draw"?)

Target creature you control fights target creature you don't control. When the creature you don't control dies this turn, if the creature you do control is still on the battlefield, draw a card.

I like it. Flawed, yes, but its got neat ideas. You're welcome to not like it, but your personal opinion doesn't define its success or failure.
