Inspired by Vodalian Mage, clearly.

may be cleaner (and follow equipment) by saying: Attached Land has ": Counter target spell unless its controller pays ."

Yikes! That's a lot different to the Vodalian Mage / Disruptive Student / Disruptive Pitmage family.

Kinda. But it's not that often that opponents cast more than one spell a turn; and it hits you too - so it's probably actually a bit weaker. In exchange for always being there for when they do cast lots of stuff, of course.

Scary for control.

It's roughly equivalent to "Each player sacrifices a land" which ... I didn't put in the set yet; but there's lots of other land destruction.

I agree it's good. Is it brokenly so though?

Technically doesn't do anything if you have Seeker of Skybreak in play, while Disruptive Student does... so not a strict upgrade, though, I agree, a stronger card.

I don't know... it does effect you, doesn't it? The comparison to Stone Rain is scary for blue... but this is a Stone Rain that you can Shatter... which, now that I think about it, would be a good idea for red nowadays... an O-Stone LD spell for .

If all your LD spells are 4cc or more, then I wouldn't worry too hard over it, since this artifact will stop you from casting them, and you can't curve them efficiently. If, however, you got a bunch of situational 3s, then I'd be worried.

This is just Sphere of Resistance with enchant land and costing an extra . Sphere effects even see Vintage play, so there's a case to be made that is undercosted for the effect. Modern offshoots of the effect tend to leave an out like Lodestone Golem or Thalia, Guardian of Thraben, probably for the same reason that land destruction is virtually nonexistent in those sets.

So - powerful; probably should be moved to the rare slot; but possibly a reasonable power for the set?
