Cascade Fetch Land 2
Land T, Sacrifice Cascade Fetch Land: Sacrifice a land. Reveal cards from the top of your library until you reveal a land. Put that land onto the battlefield and the rest of the cards revealed this way on the bottom of your library in a random order.
Now you lose something. I thought about paying life, but then it's too much like fetch lands. I thought about sacrificing a basic land, but this is already random.
Any dual land that can be fetched by fetch lands untapped has to have some drawback like the shocklands.. or they will be much better than the originaL duals...
Is WoTC not allowed to make better dual lands by the Reserved list?
I think that the closest possible dual is this: When it enters the battlefield, you lose 1 life. What drawback is smaller than losing 1 life, one time only?
Or this: As long as this land is on the battlefield, it is both types.
But both are way too good for standard and modern.
My other idea of losing and gaining life is unprintable because it's just stupid to make a card that triggers iself for nothing.

Land
T: Add C.
1, T, Sacrifice Renewed Frontier: Put a land card from your hand onto the battlefield.
Much cleaner now. Less text too.
Land
T, Sacrifice Cascade Fetch Land: Sacrifice a land. Reveal cards from the top of your library until you reveal a land. Put that land onto the battlefield and the rest of the cards revealed this way on the bottom of your library in a random order.
Now you lose something. I thought about paying life, but then it's too much like fetch lands. I thought about sacrificing a basic land, but this is already random.
I think that the closest possible dual is this: When it enters the battlefield, you lose 1 life. What drawback is smaller than losing 1 life, one time only?
Or this: As long as this land is on the battlefield, it is both types.
But both are way too good for standard and modern.
My other idea of losing and gaining life is unprintable because it's just stupid to make a card that triggers iself for nothing.
