The Brothers' War

Hurkyl, Master Wizard | Legendary Creature | Human Wizard Advisor | At the beginning of your end step, if you've cast a noncreature spell this turn, reveal the top five cards of your library. For each card type among noncreature spells you've cast this turn, you may put a card of that type from among the revealed cards into your hand. Put the rest on the bottom of your library in a random order. | Randy Vargas

Skystrike Officer | Creature | Human Soldier | Flying Whenever Skystrike Officer attacks, create a 1/1 colorless Soldier artifact creature token. Tap three untapped Soldiers you control: Draw a card. | Diego Gisbert

Third Path Savant | Creature | Human Wizard | {7}: Draw two cards. | Artur Treffner

Urza, Powerstone Prodigy | Legendary Creature | Human Artificer | Vigilance {1}, {T}: Draw a card, then discard a card. Whenever you discard one or more artifact cards, create a tapped Powerstone token. This ability triggers only once each turn. (The token is an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") | Donato Giancola

Wing Commando | Creature | Human Soldier | Flying Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.) | David Auden Nash

Urza, Lord Protector | Legendary Creature | Human Artificer | Artifact, instant, and sorcery spells you cast cost {1} less to cast. {7}: If you both own and control Urza, Lord Protector and an artifact named The Mightstone and Weakstone, exile them, then meld them into Urza, Planeswalker. Activate only as a sorcery. | Ryan Pancoast
