Hello!

I have noticed that tons of new players don't understand how important nonbasic lands are. In many, many games, my inexperienced opponents concede because they kept a hand without the necessary lands to cast their spells. They might keep a hand with only basic Plains in a red-white deck, and then scoop 3 turns later. It's even worse in five-color Brawl decks, when a new player runs mostly basics and then has an incredibly hard time casting anything at all.

My idea? Put a helpful pop-up window in the deck builder. If a player has only basic lands in their deck, give them a gentle reminder about how important nonbasic (two color) lands are. The more colors in the deck, the more important this is. You could remind them that there are plenty of nonbasic lands that can be crafted at common and uncommon.

It would also be helpful to introduce a pop-up window if a player is considering keeping a hand which doesn't allow them to play most or all of the spells in their hand. Learning to mulligan correctly takes time, but it's so important. I hate to see new players losing on turn 3 because they took a very bad hand.

These pop-ups could be turned off, so veteran players don't need to be distracted by them.

Thanks for your time, and have a great day!
