Just a silly question, can you run 99 Relentless Rats in commander? Maybe that and Sphinx of the Chimes and some juicy commander that plays off creature types.

    You may note that there are those who would argue that playing relentless rats in this way, is against the spirt of EDH. – Pow-Ian Jun 6 '13 at 20:02
  • I don't think it's a very effective strategy anyways. I've heard playing Iona is against the spirit of playing EDH :p. It would be more of a gag deck than anything else. – Mitch D Jun 6 '13 at 20:08
  • @MitchD It depends entirely who you play with, but I could see people not really liking it even as an ineffective gag deck - either you'll sit there and waste time in a predictable way, or (depending on what you're planning) you'll pull out your silly combo and end the game in an unfun way. – Cascabel Jun 6 '13 at 20:17

    Also, good luck casting one if your deck is 99 rats :) – Ivar Jan 10 '14 at 19:36

Yes, you can, for the same reason you can in other formats.

The first Golden Rule:

101.1. Whenever a card’s text directly contradicts these rules, the card takes precedence. The card overrides only the rule that applies to that specific situation. The only exception is that a player can concede the game at any time (see rule 104.3a).

They'd have to ban or restrict the card to limit its use, but it's legal in that format.

  • Awesome! Thank you kindly, good sir. – Mitch D Jun 6 '13 at 19:52

Sheldon (EDH Rules Committee) has answered this question directly.

The RC has discussed it and for the time being thinks that multiple Rats is OK. We reserve the right to change our minds down the road.

Although some rules differ from the official MtG rules (i.e. "outside the game" ,Living Wish, is handled differently than other casual formats), Relentless Rats' ability is covered in CR 112.6m. If Relentless Rats were banned in EDH, you couldn't use any copies, but since it isn't you may use any amount from 0-99 copies because [CR 112.6m] specifically allows you to ignore [CR 903.5b].

112.6m An ability that modifies the rules for deck construction functions before the game begins. Such an ability modifies not just the Comprehensive Rules, but also the Magic: The Gathering Tournament Rules and any other documents that set the deck construction rules for a specific Constructed format. However, such an ability can’t affect the format legality of a card, including whether it’s banned or restricted.


903.1. In the Commander variant, each deck is led by a legendary creature designated as that deck’s commander. The Commander variant was created and popularized by fans; an independent rules committee maintains additional resources at http://mtgcommander.net. The Commander variant uses all the normal rules for a Magic game, with the following additions.

903.5b Other than basic lands, each card in a Commander deck must have a different English name.

    Props for finding that. mtgcommander.net forums are really, really annoying to search. – Alex P Jun 7 '13 at 3:21

There's two answers to that question, depending on how you read it.

  1. Can you put 99 cards named Relentless Rats into a commander deck.

Yes you can, Relentless rats is one of the 16 cards that you can have more than one copy of in your deck (the 11 different basic lands, Relentless Rats, Rat Colony, Shadowborn Apostle, Seven Dwarves, Persistent Petitioner). The rules specify you can have any number of copies of basic lands, and the cards themselves specify you can have any number (or specifically 7 for the dwarves) of the other 5. The very first rule in magic, Rule 101.1, specifies that you follow the card's oracle text when it conflicts with the rules (after all most abilities add to or remove effects of other rules, like Haste removing the effect of summoning sickness).

  1. Can you play a deck with 99 Relentless Rats.

Nope, the deck is legal, but with 99 Relentless Rats in it, that means you have nothing in the deck except Relentless Rats, there's no way to actually play the deck. If you want to build a deck like that, you probably want to top out at 70 Relentless Rats, if you play nothing but the rats and land.

    "there's no way to actually play the deck" Of course there is. Not sure what definition of "play" includes "will have a realistic chance to win with". You still draw a card every turn, etc. There was even a time in MTGs history when a deck consisting of 1000 lands and nothing else was actually competitive! – GendoIkari 2 days ago
  • @GendoIkari You can use the definition Magic uses for the word "play". None of the cards in the deck would be able to be played (unless by some chance an opponent uses something like show and tell, but analysis like this needs to be done in a vacuum) Since none of the components of the deck can be played by that definition, the deck as a whole could be said to be unplayable. A deck of nothing but land would be playable by that definition, you can still play the land, one per turn. – Andrew 2 days ago
  • I think there's a clear distinction between asking "can you play a deck with Relentless Rats" and "is there a way to play a Relentless Rats if your deck is just 99 Relentless Rats"? Nothing in the OP suggests the later question. – GendoIkari 2 days ago

    Note that the "deck of all lands" that was "played' historically could have just as easily been a deck of all Relentless Rats for the exact same effect. Playing a land wasn't relevant to the strategy. – GendoIkari 2 days ago
  • @GendoIkari Can uoi explain the 1000 land deck? – Acccumulation 16 hours ago

You absolutely cannot have 99 Relentless Rats in Commander. It's madness. The card costs 3 mana. How are you even going to cast one the whole game with no lands? Commander is a 100 card deck no more no less.

    There is no rule in Magic that your deck needs to be playable. You absolutely can build a deck with nothing but a commander and relentless rats. You'll just lose with it. – Arcanist Lupus 2 days ago
  • "Can" and "should" are two different questions. – ryanyuyu 2 days ago
  • @ArcanistLupus to be fair the question does use the word play, and depending on which definition of the word you use, a deck with no lands and no moxes is unplayable. – Andrew 2 days ago
