I just signed up with Deckbox and imported my whole collection over. What are the P and T columns? The numbers don't seem to correlate to anything with the cards, and there's no tooltip when you hover over them. It's probably something super obvious that I'm gonna slap my forehead over, but I cannot find anything online saying what they are.

Power and Toughness for creatures.

Yep. Slapping my forehead on that one. LOL I didn't even notice it was only indicated on creatures. Thank you!
