Eek. Seems very powerful. It's searchable by the entire Scalding Tarn/Flooded Strand cycle, as well as Farseek, which makes the next two points a bit more frightening: It's another post for Cloudpost, bringing the total up to 16 or 20 (!). It enables Urza's Tower, Urza's Mine, or Urza's Power Plant without the need of both others. I'm not too worried about it being a Desert or a gate.

I like this effect. I had it on an equipment in my "cares about card types" set: Uniscape Bracers.

It's nice; but it's, at least, an ETB penta-land. Which is a bit too good even before Link's objections come into it.

That's true, actually - it does rather obsolete Rupture Spire, Grand Coliseum, and probably more.

­Archaeological Dig, Abandoned Outpost (cycle), Forsaken City, Transguild Promenade...

Heck, If this has existed back in Unlimited; it would be an actual question whether to run this instead of some of the true dual lands.

Awww, now it's Rainbow Vale. Which I might be the only person ever to have loved.

Yikes. I knew it was broken, but didn't realize this would be the response. How about I make into a slightly better Rainbow Vale?

Well, I guess it already has a niche as a searchable outpost / funny-land enabler. And rainbow vale was largely hated due to being in fallen empires and thus tarnished with the brush of "Terrible and massively overprinted".

So maybe that's OK?
