The Brothers' War

Forging the Anchor | Sorcery | | Look at the top five cards of your library. You may reveal any number of artifact cards from among them and put the revealed cards into your hand. Put the rest on the bottom of your library in a random order. | Liiga Smilshkalne

Involuntary Cooldown | Sorcery | | Tap up to two target artifacts and/or creatures. Put two stun counters on each of them. (If a permanent with a stun counter would become untapped, remove one from it instead.) | Eelis Kyttanen

Splitting the Powerstone | Sorcery | | As an additional cost to cast this spell, sacrifice an artifact. Create two tapped Powerstone tokens. If the sacrificed artifact was legendary, draw a card. (The tokens are artifacts with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") | Campbell White
