New Casual Format: Type V

After playing endless hours of type four with my friends, I decided it was time for a new format. I came up with something that so far has only been called Type Five. If somebody can think of a more clever title, or knows of somebody who invented this format before I did (other than the obvious Marvel influence), please let me know.

Anyways, here are the main rules for the format:
1. You may play any non-land card in your hand as a basic land with the basic land types of each of the colors in that card's mana cost.
2. You cannot mulligan.

This obviously causes differences in play from regular Magic, but I'll just point out the following:
1. Turns are more complicated, as you have decide every turn what you're going to give up for mana.
2. Mana flood goes away.
3. Mana screw mostly goes away (double color costs in mutli-color decks will continue to be a problem).
4. Card quantity becomes more important than card quality, as you don't have to filter out land.

It's possible to use this rule and play it a constructed format, but we've only used it in conjunction with draft, with the following rules:
1. The draft packs are selected at random from a large stack
2. The large stack must be Highlander (i.e. only one of each card).
3. If a booster draft, each player gets three packs of fifteen cards.
4. If a Winston draft, each player gets fifty five cards.
5. The minimum deck size is thirty.

Some things that we have noticed:
1. As with all sorts of Cube Stacks, you can't just throw in all the good blues cards and every Wrath of God variant in your binder: This will ensure that everybody plays a control deck.
2. When making the stack, don't put too many gold cards in. The problem this makes is that everybody's mana base becomes so solid that everybody at the table ends up in four or more colors. That wouldn't be bad if this was IBC, where that is a difficult challenge that is rewarded. If there are too many gold cards, people just take the best card in the pack regardless of what color it is, which takes all the strategy out of the draft.
3. The deck size of thirty is fine, unless you're playing draw (that is, three or more of things like FoF, Looter, Thirst), in which case you probably want to play four to seven more cards.
4. Cards that bounce lands, like Gush, are stupid good and have been banned from our stack.

Well, I hope that people are intrigued and play some Type V of their own. I'll gladly answer any questions that people have about the format.
