Mashup skeleton "(CA02) Land destruction " (yes, a common land destruction artifact) and... Future Sight.

Dang!

There's a really good obvious mash there; which is nice and subtle - but really belongs at uncommon.

I had envisaged this as a colourless stone rain; but maybe a millstone is actually better as a way of dumping lands into graveyards.

­Lantern of Insight suggests this isn't too expensive an effect to add to an artifact; even one that then lets you do something useful with the knowledge. Although, wow... am I about to suggest making millstone a common?

That's format warping!

I think it'll be safer, and saner, to make it a cheap one-shot. It's still pretty darn good. And.. too complex for common.

Gah, damnit. Don't have a good answer here.

For now; let's just reprint millstone. It's not like a deck benefits from having more than one in play.

Gah; entirely the wrong set!

Missing . Not sure if that's a) an accident, b) deliberate "errata", or c) deliberate intended to go with some kind of "mono artifact" type line.

­Tome Scour is fine to exist as a common, but normally unplayable. I'd love to see a format that makes it playable. Mental Note was playable because its limited format included Threshold.

Complete misremembering. I thought there was one that didn't tap; maybe that cost more?

I see the problem with making Tome Scour playable - this one almost works; except you're using it to pump up creatures etc. so it's not a wonderful synergy. And environments where milling is viable, have better stuff (like the ridiculous 'mill him for 14' god)
