This card has broken pauper (in a good-ish way).
It has allowed 3 colour decks to actually stand a chance in the format now.
I am quite a big fan of the astrolabe, and I believe that wizards wouldn't be able to print this at
as it is just too efficient at fixing when it replaces itself.
If you allow snow-basics from your land box, wouldn't this just cost
most of the time anyway?
I don't know why you would need to errata it. Plus it is another card that works well with one of my favourite white creatures:
Also, if anyone hasn't seen
Dom's post on introducing Snow Artifact aggro into your cube, you should, as it is a great read and makes you want to pick up some snow-lands next time you get the chance to give it a spin.
EDIT:
Heck, people run
Chromatic Sphere/
Chromatic Star in their lists as decent one-shot fixing. This would be the same as those but sticks around. That is obscenely efficient fixing.
