Arcums Astrolabe The most restrictive part of Arcum's Astrolabe is that you need snow mana to cast it

That's perfect for elves, goblins, wizards, knights, warriors, and yes, even Slivers

The main under-performer in this deck, if there is one (this is one of those decks where Ranger of Eos is the clear over-performer) is his fellow four, Bloodbraid Elf

Haliya, Guided by Light ($3-$6) Just a solid card, tough to go wrong

Since it doesnt have much staying power in constructed formats, $25 does seem somewhat high

The value of this is the fact that you can cast it for free by granting an opponent some life, which is potent enough that the card is banned in Pauper
