The Brothers' War

Kayla's Command | Sorcery | | Choose two — • Create a 2/2 colorless Construct artifact creature token. • Put a +1/+1 counter on a creature you control. It gains double strike until end of turn. • Search your library for a basic Plains card, reveal it, put it into your hand, then shuffle. • You gain 2 life and scry 2. | Dominik Mayer

Kayla's Reconstruction | Sorcery | | Look at the top seven cards of your library. Put up to X artifact and/or creature cards with mana value 3 or less from among them onto the battlefield. Put the rest on the bottom of your library in a random order. | Nicholas Elias

Lay Down Arms | Sorcery | | Exile target creature with mana value less than or equal to the number of Plains you control. Its controller gains 3 life. | Liiga Smilshkalne

Mass Production | Sorcery | | Create four 1/1 colorless Soldier artifact creature tokens. | Rémi Jacquot

Recommission | Sorcery | | Return target artifact or creature card with mana value 3 or less from your graveyard to the battlefield. If a creature enters the battlefield this way, it enters with an additional +1/+1 counter on it. | Andrew Mar

Repair and Recharge | Sorcery | | Return target artifact, enchantment, or planeswalker card from your graveyard to the battlefield. Create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") | Ben Wootten

Legions to Ashes | Sorcery | | Exile target nonland permanent an opponent controls and all tokens that player controls with the same name as that permanent. | Artur Nakhodkin
