Hey! Neat game~
I like the feel of the pack opening and managing the cards.
I also like the general aesthetic. It's very clean and polished!
.. I also like the news events that occur! It reminds me
Some ideas / suggestions while playing the game.
1. Might be good to have a quick hover to see the cost of the card without having to drag it to the sell pile. Or the ability to quickly see the stocks with a shortcut key or something~
2. I think the news since it happens every other day. It could be a popup and freeze the game temporarily, to let the player rest and gain their composure before having to sell again in a frenzy. (Given you have enough news content). It might also be neat to have some events with choices in there as well. like people trying to scalp you a booster set (which might be worth it at times) and you can choose whether to buy it off them or not. It could also lead to more interactivity with the world or world building.
Cheers and wish you luck.
