When Atris enters, target opponent looks at the top three cards of your library and separates them into a face-down pile and a face-up pile. Put one pile into your hand and the other into your graveyard.
Atris is a Dimir value engine that fills your hand and graveyard simultaneously every time it enters. Blink or repeatedly recast Atris to grind card advantage while feeding a reanimator or self-mill payoff, then close games with bombs you've stocked in either zone. Play a controlling game—counter, remove, and use the menace body as a chip-damage clock or commander-damage threat if built toward Voltron.
Built-in card advantage and self-mill that benefits both your hand and graveyard
Cheap, recastable commander that pairs perfectly with blink and reanimation
Menace makes it surprisingly hard to block for incremental commander damage
Excellent in graveyard-matters shells where 'milled' cards are functionally drawn
Opponents choose which pile you keep, giving you less control than true card draw
Effect is mediocre without graveyard payoffs to recoup the discarded pile
Slow and grindy—weak against fast combo and aggressive decks
Four-mana body with no immediate board impact beyond menace
Leverages Atris's menace and untaps lands for a Voltron control plan.
Add more blink enablers (Ephemerate, Restoration Angel, Eldrazi Displacer) and graveyard payoffs (Animate Dead, Jin-Gitaxias) to convert every Atris trigger into real advantage. Tighten the mana with fast rocks and dual lands, and add efficient interaction—counterspells, targeted removal, and a couple of compact win combos—so the grindy engine actually closes games before the table stabilizes.
