You may look at the top card of your library any time.
The top card of your library has plot. The plot cost is equal to its mana cost.
You may plot nonland cards from the top of your library.
Fblthp turns the top of your library into a plotting engine, letting you exile nonland cards face-up and cast them later for free spread across multiple turns. You play a value-driven mono-blue control/spellslinger deck, churning through top-deck manipulation to plot threats and answers, then unloading them in explosive 'free' turns while holding up interaction.
Generates persistent card and mana advantage by plotting spells now and casting them later for free
Ward makes Fblthp resilient and cheap to recur at three mana
Pairs perfectly with top-of-library manipulation (scry, surveil, Sensei's Divining Top effects) for total control over what you plot
Mono-blue gives access to the best counterspells, card draw, and bounce to protect the engine
Mono-blue lacks efficient removal for resolved permanents and struggles against go-wide boards
Plot is a slow, grindy strategy that can be too durdly against fast combo decks
Relies on Fblthp staying on the field to enable plotting from the top of library
Limited recursion and no access to ramp beyond artifacts/rituals
A mono-blue-friendly storm finisher fueled by free plotted spells in a single turn.
Add more top-deck control like Scroll Rack, Soothsaying, and Mirri's Guile so every plot is intentional, and lean into cost reducers and free-cast synergies to chain plotted spells. Improve the mana base with fast rocks (Sol Ring, Mana Crypt) and counterspell protection to defend Fblthp, then add a tight combo finish such as Aetherflux Reservoir or an infinite-mana payoff to convert your value engine into reliable wins.
