mtg commander precon sale Magic: The Gathering The Lost Caverns of Ixalan Deck each player chooses a legendary creature as the commander of their deck Precon of the Month Box

That means it either sold for that huge sum, or someone decided to keep it for now

Cards like Grim Lavamancer are a real pain against you and being able to take them out with Scroll is delightful

Creature - Dinosaur Plant Ramp (CTRL to add secondary) Removal Scion of Calamity Myriad (Whenever this creature attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control

So long as the revealed card has a mana value less than the spell you cast, you can cast it for free

Getting to cast Channel in Commander sounds incredibly fun, but I wouldnt expect that to happen all too often
