I'd only vote for this if it's an in-game feature. New users aren't going to find peakmonsters right away. We need more features directly in the game for a better experience.
That said, I use Peakmonsters all the time, it's the most user friendly market there is. I don't have a problem with the funds or idea, I actually like the idea. However, I'd like to see it built directly ingame.
We need an in-game "1 click" solution, you want to rent a full deck of Chaos Legion, Untamed, etc. , then the system will give you the best available market price and rent all the cards at once. If you don't like the price, you can place a bid to rent a full set that someone else can fulfill. With the build out of set rentals already ingame, I don't think it's that far fetched to streamline this.
