While this is unlikely to stop a game-ending threat, being able to stop irritating early-game plays for just one mana is not to be underrated
This will mostly be down to preference
This Chocobo Bundle contains 10 Magic: The GatheringFINAL FANTASY Play Boosters, a 12-card Chocobo Booster, 1 Traditional Foil alt-art promo card, 1 of 24 Borderless Magic: The GatheringFINAL FANTASY Scene Cards, 32 FINAL FANTASY Landmark Full-Art Basic Lands (16 Traditional Foil, 16 regular), a special Click Wheel life counter, and a Chocobo Edition card box
Most of the cards' other versions are only a couple of dollars cheaper, so even if you only have that version, it is still worth alot
You can treat a learn card as a card that has some minor value effect like draw a card or create a token that can tutor for a lesson card from your sideboard
If you gain control of a cloaked card the status of the card does not change unless noted, if it was tapped, it stays tapped, if it entered play that turn it still has summoning sickness, and you may look at it as it stays face down even if you and your opponent know what it is
