Legacy Oops, All Spells! deck
UPDATED October 12, 2025 - Nathan Lipetz
Oops, All Spells! can also be known as All Spells, The Spy (most common name in Japan), Oops, All My Spells, Landless Spy, or Landless Combo (although the last one is less preferred since it may be confused with Belcher). The strategy is high tier in Legacy & Pauper, but also sees play in Vintage, as well as fringe play in Modern & Cedh).
Overview
All Spells is a self-mill-based combo strategy built around Balustrade Spy and Undercity Informer. Oops is a very competitive deck that can win as early as turn-1 with high consistency. It is one of the most competitive Reserved List-less strategies and an excellent option for budget-limited players.
The deck is full of free mana (Elvish Spirit Guide, Simian Spirit Guide, Lotus Petal, and sometimes Chrome Mox), rituals (Dark Ritual & Cabal Ritual), and various MDFC lands (which don't count as lands because they are spells on the front-side). To protect the combo, lists play 4 Pact of Negation, 2-4 Thoughtseize and sometimes even Unmask. Sideboards are focused on beating various forms of graveyard and spell-based hate the deck suffers against.
The core strategy of Legacy Oops is to mill the player's own deck and trigger Narcomoebas, cast Cabal Therapys to clear any further interaction and return Poxwalker + trigger Bridge from Below to create an army of zombie. You then can sac 3 creatures to pay for Dread Return's flashback cost into a Thassa's Oracle to win the game with an empty library.
