"Fortify to a plains" is probably too restrictive, but checking to see what type of land is fortified seems to get the idea across is a similar way, and is common enough. That ability is probably not good enough at 1 and possibly too good at 2, however. I'd change over to 2 and 3, but gaining 3 life per turn is not common. (gaining 2 per turn was probably too much as it is.)

All right, changed to something more common appropriate. And it gets the idea of a small bonus across more clearly.

Hm. I like the sentiment, but this seems useless unless its fortified to a swamp, so it might as well be "fortify to a swamp" in the first place.

I like the "exile a card" as a restriction -- how about "exile a card sharing a color this land could produce mana of", or similar, so you may move it around, but it's still better in mono?

You know, I generally think of exiling cards from graveyards as a generally useless ability as well. But every block, they throw one of them in at common somewhere. I assume they've got their reasons, but it seems annoying when you're in a draft staring at Martyr of Bones and wondering if you would ever maindeck that guy.

If we do wish to have some amount of graveyard exiling, however, and we want fortifications to be full of tutor options... well, I assume we'd either make a graveyard exiling fortification in common or uncommon. Perhaps it's the costs that are throwing you off. Would this work better for you if cost and ?

I like this. I don't think I'd play it except in a reasonably black-heavy deck, but I think it's a useful effect. A surprising amount of decks do something graveyard-relevant, be it Auramancer, Spider Spawning, a random Firebolt or Think Twice, Ichorid, Murderous Redcap, even Arachnus Spinner. This works something like a Braidwood Cup that also occasionally proves really handy against a graveyard manipulation card.

Obviously, this card needs a change of name. Besides that, this thing is right on the money for common. Added to file.

Moved this guy up to the Uncommon slot. See Deepmine Trenches.

I agree this is very random and odd in its current form; so much so that I think the appropriate action might not be advancing rarity so much as changing completely (or removing from the slot).
