A cheaper option, perhaps, and maybe one thats more flexible than Force of Will for some decks
Kavaero is frustrating enough, but this is a big evolution on that card because it doesn't exile the copy if taken from the graveyard, and it can change the copied card each turn
However, while the move is technically valid, its still odd since our only past exposure to Lessons came with Learn attached
I fully expect the lairs to sell out within a day or two, and when people get their copies and crack them, Ill want to target the Sol Ring, Open the Armory, and Hammer of Nazahn
Please tell me in the comments below or in the Draftsim Discord
Monastery Swiftspear is very similar to Soul-Scar Mage, so it seems worth pointing out why theyre not listed together
