Hey it's me! Allie! You may know me from discord or better yet from the leaderboard!
I'm a professional software engineer and I make this site in my free time. Z2H originated as a tiny python script I was running on my laptop to pull collections and compare scores in a spreadsheet, similar to what you see on the trade page here. That script helped me climb from about rank 50 to rank 29 on the CH1 leaderboard without spending a single cent. Rather than keeping it for myself, I decided everyone should have powerful tools like it in their hands to better the Hro community as a whole.

I'm always down to trade and still chasing a few big cards, so let me know if you ever want to work out a deal!
