This is interesting. The first time I read this, I thought about Richard Tyler Blevins aka Ninja

There are many professional video game players, and even guilds these days. I have supported a few myself. This is the first time I have seen the concept on a blockchain based game.

1. There are skilled players
2. There are superlative card deck (owners)

This process likely bridges the gap, and takes the game to the next level; beyond renting. This is a good business model, let us see how well you run it :)

Because that's the tricky part.
