Fun game, took 1d 7hr to beat it, but i probably could've challenged the last champion earlier. I appreciated the aspect of figuring out how to build the deck to beat the computer.

For feedback, I would suggest updating the buttons enter tournaments/champions to include the cost even if you don't have sufficient funds. Also, I would update the wording on the champion matches so it's clear that you SPEND 100 trophies to go up against the champion. When i first attempted the battle, i thought i needed to have 100 trophies tin order to qualify to play against champion, not that it was an actual entry fee.
