They're reasonably cheap so I may pick some up, but my initial, not-having-tested-it reaction is that the card is terrible. Here are my thoughts, in no particular order:
- Recycling our own lands would probably be rare. As it is, the deck has very few ways to actively bin its own lands:
Crop Rotation, fetchlands (if you're even running them; I'm not right now), and
Glacial Chasms that you opted to let go. I can't say it would never make sense to recycle a
Glacial Chasm, but it seems pretty unlikely. Considering that the number of times you would ever Rotate your own
Cloudpost would be incredibly small (not saying that it would never happen, just that it's exceedingly unlikely), odds are you'd only retrieve a land that produced one mana. More on this later. Basically though, the card is already pretty bad because it would almost always require us to Rotate something before we'd ever get anything out of our own graveyards.
- Okay, we can dig lands out of our opponent's graveyard, too. What, then, would be there? Certainly nothing we put there ourselves.
Wasteland? Sure, but in order for it to get there, my opponent still has to get (and use) it on me. I'm running
Pithing Needle main again: ideally, I'd just as soon have my opponent not be able to use his
Wasteland at all. And speaking of
Wasteland, I'm not sure it's really that big of a deal anyway. If
Wasteland was that vital to our strategy, we'd be running them. Expanding on that, if we wanted to recur them, we'd run
Crucible of Worlds. And in a meta where
Wasteland is already everywhere, if a deck like RUG Delver can still get away with running what, 6-8 colored mana sources, then I'm inclined to believe getting hit with a
Wasteland doesn't exactly blow them out. Thus, it seems more likely to me that if we're getting lands out of their graveyard, they're probably fetchlands, which means all we're doing is accelerating by one mana. Which brings me to my next point:
- At a mana cost of 1G, if all we want to do is accelerate, we can do much better. First off, I'd always prefer pulling lands out of my deck. At 1G, here are some relevant cards
Restore would be competing with:
Edge of Autumn,
Explore,
Farseek,
Land Grant,
Life From the Loam,
Living Wish,
Rampant Growth,
Sakura-Tribe Elder,
Summer Bloom,
Sylvan Scrying. You'll note that some of those cards are awful and would have no business ever being in a Legacy deck. Yet if all I'm doing with
Restore is getting a land that produces one mana onto the battlefield, you could argue that even
Rampant Growth would actually be better as it at least has the decency to pull that land out of my deck.
- Last, and perhaps most importantly,
Deathrite Shaman eats
Restore for lunch.
Again, I haven't tested it yet, but in my (obviously not expert) analysis, "situationally worse than a
Rampant Growth and utterly useless against a
Deathrite Shaman" is not where we want to be in power level.
