Sunfall | Sorcery | | Exile all creatures. Incubate X, where X is the number of creatures exiled this way. (Create an Incubator token with X +1/+1 counters on it and "{2}: Transform this artifact." It transforms into a 0/0 Phyrexian artifact creature.) | Kasia 'Kafis' Zielińska

Breach the Multiverse | Sorcery | | Each player mills ten cards. For each player, choose a creature or planeswalker card in that player's graveyard. Put those cards onto the battlefield under your control. Then each creature you control becomes a Phyrexian in addition to its other types. | Liiga Smilshkalne

Into the Fire | Sorcery | | Choose one — • Into the Fire deals 2 damage to each creature, planeswalker, and battle. • Put any number of cards from your hand on the bottom of your library, then draw that many cards plus one. | Grzegorz Rutkowski

Nahiri's Warcrafting | Sorcery | | Nahiri's Warcrafting deals 5 damage to target creature, planeswalker, or battle. Look at the top X cards of your library, where X is the excess damage dealt this way. You may exile one of those cards. Put the rest on the bottom of your library in a random order. You may play the exiled card this turn. | Zara Alfonso

Glistening Dawn | Sorcery | | Incubate X twice, where X is the number of lands you control. (To incubate X, create an incubator token with X +1/+1 counters on it and "{2}: Transform this artifact." It transforms into a 0/0 Phyrexian artifact creature.) | Chris Ostrowski
