What's the ruling on Dryad Arbor?

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!

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

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.

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

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

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

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

Actually, what about morph cards?

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.

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

Ok, awesome.

Are cards with flashback legal?

Godhead_Initiated Yes

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

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

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

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.

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?

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.

Update: new card minimum is 75 cards

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.
