While Wizards of the Coast states that deck lists are required to be submitted, they never really specified how.
Congrats to this Florida man on turning in a tasty version of his Eldrazi Tron deck.
So fun fact, found out at work that a Florida player submitted his decklist at a rptq on a cake with frosting. Can confirm with pics pic.twitter.com/PNTLAMvG2O
