­Into the North + Sacrificial Pawn

Search for a snow land, and a sacrifice enabler / truly horrific infinite combo thingy / normally kinda just 'Mill a card: Regenerate'

Ok; gotta keep the snow part. Snow is too rare and lovely to ditch. Now, how about "When this dies, search a snow permanent into play?" without the "You can have any number of these" clause, the worst abuses are removed; and using it as a normal search card becomes sensible.

And I was going to say that the nastiest thing you could search out was a 3/3 flyer; and price it accordingly - but then Gargantuan Gorilla magilla'd his way to the front and demanded to be nerfed. (Ok, there's a few other bigguns too) So. Adding a CMC limit. UGLY WORDING. So it went rare. Oh, an d I missed the 'then shuffle your library'.

Imaginary rules team? Just tack that onto the definition of searching a library, would you?

­Gargantuan Gorilla isn't actually snow.

Gatherer lied to me!

Anyway; Phyrexian Snowcrusher, Rimescale Dragon...

There's a buncha stuff that would mean this had to have CMC6+ to not have some kind of restriction.

without a P/T how can it die? or even be on the battlefield? lol

Rather than the "tap any number of lands [you control]" wording, how about "search your library for a snow creature card, reveal it, and put it into your hand"? Or perhaps "search your library for a snow creature card, pay its mana cost, and put that card onto the battlefield"?
