Going the path of a professional Magic: the Gathering gamer requires a lot of preparation. One of them is the decklist.
So what is a Magic: the Gathering decklist? Like any other card games, a decklist is a list of cards that you will be playing with in a tournament. It is separated into Creatures, Lands, Planeswalkers and any other types. A standard decklist requires a minimum of 60 cards in the main deck and a sideboard of 15 cards including the companion if you are using one.
So how does one prepare a decklist. For casual games, it is very easy, just fill out the form and play the game using the cards that you listed on the form. It is not even required for most casual games.
At the professional level, making a decklist is like taking an exam. You prepare by checking the details of the upcoming tournament such as the date, format, and possible meta. Prepare the draft of your decklist and discuss it with your friends or teammates. It is always best to have a second opinion of your card choices for both main deck and sideboard. Sometimes, the deck that you are used to playing in the local community, may need some changes of a few cards to compete in the larger tournaments. Large tournaments have more archetypes as compared to a local FNM of eight(8) to twenty(20) players. If you don’t get a bye on large tournaments, there is even a possibility of encountering a lot of rogue decks in the early rounds. Discussing your card choices with your friends and teammates, will help you in optimizing your deck and thus giving you a better fighting chance to win in the said tournament.
It is always best to finalize your decklist and submit it before the deadline set by the organizer. Last minute changes on the decklist is fine, however, in most cases you may end up losing focus or messing up with your strategy. One thing to keep in mind for those aspiring on the professional level is that in large tournaments there is a random deck check done by the judges or organizers of the event. A discrepancy of even just one(1) card from your decklist in comparison to your actual deck, can cause you a game or match loss. Make sure that the deck you are using is the same as the decklist that you have submitted one hundred percent(100%).
For MTG Arena tournaments, decklist submission is now easier than before. Tournament organizers nowadays have come up with simple ways for deck registration. Instead of submitting by paper, most decklist submission now can be done by clicking the export button on your MTG Arena and pasting your decklist on their website.
Now that you have submitted your decklist, go out there, enjoy the game and be confident. Best of all, thank your friends and teammates and support each other!
