gusgrey came up with most of the Colossus formats rules, check them out below before you comment on this deck

Anyways, I thought this was pretty cool and I'm pretty excited to try this out. I will never turn down suggestions, so go ahead and comment if you have any.

Deck Rules:

101.1 - All Colossus decks must meet a minimum of 75 cards to be considered legal.

102.1 - Each deck must contain a minimum of two colors.

102.2 - Colorless is not considered to be a color.

102.3 - A deck is considered multi-colored when at least two of the included colors meet a minimum of 4 cards for each of those colors.

103.1 - All cards must have a converted mana cost of 7 or over, except for noncreature artifact spells that tap for mana and have no other effects nor abilities. For example, Sol Ring is legal whereas Azorius Cluestone is not due to its second ability, which does not tap for mana.

104.1 - Cards with X in the mana cost must be paid with a minimum of 7 mana total. This does not mean that X itself has to be 7 mana or greater. For example, you can cast Secure the Wastes by paying the one white mana that is required and 6 mana of any color towards the X cost for a total of 7.

104.2 - Cards with XX or XXX in the mana cost must be cast with a minimum of 7 total.

105.2 - Cards with alternative mana costs that are less than 7, such as cards with suspend and morph, are legal as long as the original converted mana cost of the card is 7. For example, Maelstrom Djinn is legal, but Backslide is not.

While Playing:

201.1 - Each player begins the game with 60 life.

202.1 - The game continues like a typical casual, standard, or modern game and no changes have been made to the general gameplay.

More rulings will be added as questions and unintentional issues arise.The format was designed by mostly gusgrey and only a little bit by me. The written rules were edited and polished up by SecondRate.

What's the ruling on Dryad Arbor?

October 30, 2017 10:34 a.m.

Just an idea for the format rulings, you could have it so that each player starts off with X basic lands (I'd say 6) at the beginning of the game!

October 30, 2017 11:34 a.m.

Plus, a suggestion for the deck, storage lands could be immensely useful for your purpose, if you don't start off with lands on the battlefield. You could spend all of your mana on the lands then blow it all once you can afford the creatures!

Ignore the Crucible of the Spirit Dragon, didn't read the whole card

October 30, 2017 11:40 a.m.

Just as a note, any card with X converted mana cost, X=0. I don't know if you're making an exception for cards with costs that are X, but for example, Quarantine Field's CMC is 2.

October 30, 2017 2:19 p.m.

icehit6 we understand that, that's why we made a rule that you must pay 8 total mana when you use cards with X in the mana cost.

October 30, 2017 4:09 p.m.

Mr.Beaver It's a land, so it is legal to play

October 30, 2017 4:12 p.m.

ACDAMAN I like the idea of starting off with a certain amount of lands. It would certainly help quicken the game.

October 30, 2017 4:13 p.m.

So this played against another player with a Colossus deck? Also, is this like type four?

December 26, 2017 5:47 a.m.

Is Worn Powerstone legal? And what about cards with Suspend?

December 26, 2017 5:49 a.m.

Actually, what about morph cards?

December 26, 2017 5:49 a.m.

Godhead_Initiated, Worn Powerstone is legal because it only taps for mana and has no other abilities, but I will have to get back to you later tonight about your other questions.

December 26, 2017 1:26 p.m.

Godhead_Initiated, both morph and suspend cards with alternative costs are allowed as long as the original cost of the card is 7cmc.

December 26, 2017 8:31 p.m.

Ok, awesome.

December 27, 2017 1:09 a.m.

Are cards with flashback legal?

December 27, 2017 1:12 a.m.
December 27, 2017 1:33 a.m.

I built a rough idea of the colossus format, and I want to check with you if it is legal by your rulings.

December 27, 2017 1:39 a.m.

Godhead_Initiated Oh sweet, share it with me or tag it. I'd love to see it

December 27, 2017 1:41 a.m.

What exactly are you counting as a two-colored deck here? I noticed that you only run four non-green spells.

December 29, 2017 3:33 a.m.

brewtzar You can have as much or as little of each color that you want, but I would say that as long as you have no less than a playset of a single color, it counts as two-color. Colorless, of course, does not count as a color, but may be included. After the game that I played tonight using my friend's deck for this format, I will definitely be looking into more white cards to add for better defense against my other friend's deck.

December 29, 2017 11:01 p.m.
That third rule states that All cards must have a cmc 7 or over, unless they tap for mana and do not have any other effects. and you cite Sol Ring as being legal.

Comparatively, rule 5 states that Creatures under 7 cmc that tap for mana are also illegal. meaning a mana dork like Elvish Mystic is illegal.

My question is, the aforementioned rules make no explanation into why an artifact mana rock is legal to use but a creature mana dork is not. Why the conflicting rules? It seems odd to allow noncreature spells that tap for mana but not creature spells.

December 30, 2017 12:50 a.m.

Because creatures are just that. Dryad Arbor is the one exception, which IMO should be banned in this format. If it's a creature that can tap for mana, it still has the ability to attack, defend, and wear equipment/enchantments (yes I know cards exist to do that to mana rocks). It's to encourage all the most ridiculous of magic.

_raeofsunlight: Just a clarification on X spells. The total mana spent has to be 7 correct? So I could Banefire for 6 T7?

December 30, 2017 11:47 a.m.

SecondRate, epajula pretty much answered that (if you didnt already see that.

Mana rocks are simple and have no other abilities aside from giving mana, while mana dorks can attack and do other things, making them illegal because they are creatures under 7 cmc.

epajula Yes, cards with X must be paid with seven mana total.

Ill try to update the rulings to see if I can make things clearer.

December 30, 2017 1:13 p.m.

Update: new card minimum is 75 cards

December 30, 2017 1:26 p.m.

If you do start with extra land in the beginning make sure you up the life totals. If that is a rule that goes through I would only start with 2, no more than 3, lands so that mana rocks are still relevant.

December 30, 2017 6:32 p.m.

My question was mainly meant to push a more clearly written rule set. I would be willing to help if you dont have the time. O.O I really need more things to do regarding magic, I live in rural Kentucky with only one person to physically play the game with. Anyway! Im gonna start building my colossal deck now. Would anyone like to be tagged into it so there are more instances of colossus decks floating around?

December 30, 2017 6:58 p.m.

I would

December 30, 2017 7:43 p.m.

Add me as well

December 30, 2017 9:40 p.m.

Cloudpost and Tron lands are banned, right? That just seems OP in a format like this. 12-post seems like it must automatically be the core of your deck or you lose.

December 31, 2017 2:58 a.m.

HR19 No lands are banned or have limitations... for now. It does seem OP for this, but it's not necessarily a must. I think that would depend more on your playgroup than anything else. In my playgroup we don't really use anything like that and aim to find other forms of ramp.

December 31, 2017 3:28 a.m.

I never thought of 12 post for deck building.

December 31, 2017 2:32 p.m.

Quick question, cabal coffers is not legal right?

December 31, 2017 2:46 p.m.

Is Sundering Titan legal?

December 31, 2017 3:53 p.m.

btw, tron seems busted in this format imo.

December 31, 2017 3:54 p.m.

Godhead_Initiated, all lands are legal and are not given limitations in any way (for the moment)

Wasablime, sundering titan is legal because its converted mana cost is above 7

December 31, 2017 5:35 p.m.

Congrats on the new format!

January 5, 2018 9:43 p.m.

Annihalator breaks this format. Whoever plays the first creature with annihalator that attacks wins.

January 6, 2018 12:59 a.m.

Not true. It's just pretty strong.

January 6, 2018 7:32 a.m.

You know, count me interested in this idea. I may wait to make my own just yet, but I'll be thinking of what you could use for yours for now, so keep an ear out.
