Whenever another nontoken creature you control enters, investigate.
, Sacrifice X Clues: Target opponent reveals the top X cards of their library. You may put a nonland permanent card with mana value X or less from among them onto the battlefield under your control. That player puts the rest on the bottom of their library in a random order.
Lonis turns every creature you cast into a Clue token, then converts a pile of Clues into stolen permanents off opponents' decks. You flood the board with cheap nontoken creatures and Clue-generators early, build a stockpile of Clues, then activate Lonis to swing the game by stealing bombs you didn't even pay for. The deck wins by snowballing card and board advantage until you out-resource the table.
Generates relentless card advantage from Clues without committing extra cards
Steals opponents' best permanents, often for free, swinging multiple board states at once
Cheap two-mana commander that's easy to recast and slots into any creature-heavy GU shell
Synergizes with both go-wide creature strategies and Clue/artifact token payoffs
Heavily commander-dependent; without Lonis the deck just makes spare Clues
The steal ability is slow, needs Lonis untapped plus a hoard of Clues, and is variance-based on what's revealed
Light on interaction native to GU; can struggle against fast combo and heavy removal
Vulnerable to artifact wipes and graveyard/token hate that erase your Clue economy
Turns your wide creature board into mana, letting you sacrifice big Clue piles and cast bombs in the same turn.
Add fast mana (Sol Ring, Arcane Signet, Fellwar Stone) and more blink/sac engines like Eldraine Charm and Brudiclad-style multipliers to crank Clue output. Tighten the curve with cheap value creatures that reliably trigger Lonis, and include Academy Manufactor plus Anointed Procession effects to double down. Finish with a payoff line—Craterhoof Behemoth, Overwhelming Stampede, or an artifact-sacrifice drain—so the snowball converts into a clean kill.
