If you have been thinking about making a “Magic: The Gathering” commander deck, there are a couple of things to keep in mind. Commander decks are one of the most fun forms of magic the gathering. Commander was originally invented by the players of magic the gathering and then was adapted by the professional world of mtg.
The first thing you should know about Commander Decks, is they include one hundred cards each. This includes a legendary creature that is put into the command zone. The creature you choose as a commander must be legendary, or if it is older its creature type must be legend. Illusions which are all creature types at once do not count unless they also say legend. Out of the one hundred cards you can only have one of each name except for basic lands. This means if you have two “Elvish Mystics” you can only put one of those cards in your deck.
Almost all commander decks rely on the commander for almost everything. All the cards inside the deck have something to do with the commander’s abilities. Also, all cards in your deck can only be the color or colors of your commander. You can not use something that is another color even if you have ways of playing it without paying the mana costs.
If you do not have a lot of money or cards, but still want to make one there are a couple ways to do this. The most effective way is to buy one of the “Theros” gods, which are a legendary enchantment creature, and pack the rest of the deck with any creatures you can find. The “Theros” gods are not to picky and just need a bunch of creatures to make them strong competitive decks.
Another way to make a deck that is a little more costly, but not as costly as some decks are is to buy a pre-constructed deck and tear it apart. leave the best cards in the deck, and substitute the others for the best cards you already own.
Many players pick commanders with several mana types in their casting cost. While this greatly increases the number of cards they can choose to put in the deck, it is a faulty plan, as having to many colors can leave you “mana Screwed” meaning you do not have the right type, or enough mana to cast the spells in your hand.
Since it is your first deck, you will want to keep it simple, and prepare to lose, as with everything it takes practice and patients to master.
