- When you play a card that applies to the whole turn (e.g. Celestial Armor), please pin the card to the playfield so I can remember it's active. Or at least print the name of the status effect somewhere on the UI.

- Please improve deck navigation. The current format is linear and has the scroll buttons right over the cards. I'm worried about mis-clicking a card and banishing it. Consider a vertically-scrolling tabular format as well. Decks aren't huge so we likely don't need a bunch of filters, but those would be nice too.

- Turbo mode. Faster animations.
