Sigarda's Aid: This little enchantment gives the deck an unbelievable boost on tempo. Equipments are normally a two-turn investment--one turn to cast, and another to equip--but
Sigarda's Aid not only allows you to skip right over equip costs, it lets you cast equipment
on your opponent's turn. All in all, this is unbelievable value for
.
Basilisk Collar: Deathtouch and lifelink. Need I say more? This deters blockers and attackers like no other. Deathtouch makes the equipped creature as big as it needs to be to take down anything, and having lifelink tacked on is just icing on the cake. Mini Wurmcoil Engine, amirite?
Batterskull: Curve topper and finisher for the deck. Batterskull gives value straight away with its living weapon ability, and then goes on to buff other creatures through the roof. Once again, a combination of two great abilities, vigilance and lifelink, is nothing to sneeze at.
Sword of Body and Mind: This sword is all sorts of goofy and dangerous. Milling ten and getting a 2/2 token with one hit is ridiculous, not to mention a +2/+2 buff. This sword is just straight value.
Sword of Fire and Ice: The most popular of the Sword of X and Y cycle, and for good reason. Protection from makes protection from some of the best cheap removal, coughcoughLightning Boltcough and getting to Shock and draw a card upon a connection with a player is spectacular. Card advantage is one of the most important things in Magic, and this sword provides it.
Sword of War and Peace: On terms of removal protection, this sword is an all star. Not only does it prevent removal like the aforementioned bolt, but it stops things like Path to Exile or Pacifism. You name it, this sword probably protects it. And the connection bonus just crazy. Disregarding regular comabt damage, this sword has potential to create a lifeswing of 14. Think about that for a second.
