So inspired by a Cardmarket video, my partner, our friend and I are attempting a more extreme ultrabudget Commander deck challenge than any we've done before:
2€ Commander Deck Challenge
A 100 card Commander deck, where the total value of the lowest reasonable prices of cards* in the deck comes to 2€ or less
"lowest reasonable prices": you need to be able to find several (~5+) sellers offering the card at the price point at which you're counting it against your budget; just one listing for that price isn't enough
Budget does not include basic lands, but does include everything else including any nonbasic lands and the commander
You do not need to actually buy/play the printing you found at the lowest price point (aesthetic variations are fine, so long as a printing exists at the price point you are budgeting that card as)
