I am having trouble finding which cards I need for set redemption in this case specifically M19. Do I need all the cards from planeswalker and welcome decks? Thank you so much!
If people are sick of reading about stuff just stop taking part. You have 100% control over what you read. Simic Ascendancy isn't going to get banned just because you didn't tell someone to shut up on the internet.
