I haven't played commander at all but do you only use one of the legendary you are going to use in your whole deck? And dose it come out right away or do u have to draw it? Last question is there a differant legendary that has white in it that's good for tokens besides kemba? Or just in general a good one for tokens
You're better off asking these questions in the "Commander" section of this forum.
True
To play commander, you build a 100 deck with no repeat copies of any card (other than basic lands).
Before the game begins, you select one legendary creature from your deck to be your commander. This card is placed face-up in a special zone (the "command zone") where you may summon it from any time that you normally would be able to (usually during your main phase unless it has flash). You must pay its mana cost to cast it, as normal.
Whenever your commander dies or is exiled, you may choose to have it return to the command zone instead. However, each time you do, an additional {2} is added to its mana cost.
In addition, each player starts with 40 life.
Other info (if I missed anything) is in the sticky up top. Welcome to the format, it's a super fun multiplayer way to play!
