Gemstone Mine

This sucka is an excellent card in a fast multi-colored combo deck where you probly wont be using it very many times before you fire off the combo.

Although not the best way to solidify your mana base, this card works great if you want to splash in a 3rd or 4th color, and works well in 3 color decks, giving them the mana diversity to case multi-coloroed spells before they have to start casting spells to solidify their mana base. I think that City of Brass, however, would be a better choice.

one of my favorite lands. i have it in my 5 color control deck and its awesome

As far as some ish that might be more applicable to Extended, I'm really toying about using this in a deck with Glittering Wish and Life from the Loam. That's all I'm saying, go get yr own ideas.

bounce lands!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

poeple think about what deck uses this um 5c stax and what does stax use crucible so where is the drawback.

Gemstone mine is a perfect peice to any madness build, Use it three times, destroy it, and fetch it back withEternal witness!

play two of these in a five-color 1.5 deck. i've enjoyed this land ever since it came out and have always wondered a bit why it wasn't more expensive. since that's how i'm gauging it popularity. anyway, i've enjoyed it over the years and even more when 'mox diamond' was allowed in 1.5 play. but it isn't, so we have to move on.
in conclusion, an excellent land worth a looksee and a couple or four might help smooth out the rough edges that are hurting so bad on your mana curve. ciao!
