Just supporting the Mountainwalk in this set.

Yowsers. Forget about enabling mountain walk; this will utterly destroy an opponents mana base; taking two lands off the table.

I mean, ok, yes, Blood Moon does that too; but still. This is going to be very good. Upcost by a half mana maybe?

It's 'in addition' to its other types, not a replacement. The second ability isn't any more powerful than Aquitect's Will technically.

I was afraid people would misread this, though. Maybe reminder text is appropriate.

"(If an Island is enchanted, it becomes a 'Land - Island Mountain'.)"

Hm. Not pretty, though.

"(It can tap for or for any mana it was previously able to produce.)"?

Changed the card to be what Vitenka expected it to be. I might change it back, depending on what the set needs... but honestly, the set will probably require a few more expensive cards, what with me shaving some colorless from the occasional common and uncommon...
