You start the competition with a 40 card MONO deck of your choosing - No Shields. No weapons. No Permanents. No Spells. Creature cards and Pillars/Pendulums only. Your mark must be the same as your pillars. Ultra-mono
You will fight a randomly chosen opponent each round. Rounds are over when one you or your opponent wins 3 duels. After each round, "store credits" will be awarded as: 5 credits per duel lost, 10 credits per duel won. Yes, that means you can reap the most coin by losing 2 and winning 3 duels per round! You may spend or save the credits you have earned.
Shopping Prices:
1 - Buy a creature card for your deck
3 - Buy a spell card for your deck
5 - Upgrade a card you have
5 - Buy a weapon card

10 - Change your mark
You may switch decks between duels, IF you have enough cards to do so. You may not go shopping between duels (per round).
If you lose 3 rounds, you are eliminated from the competition.
