Dack's Duplicate card art
Dack's Duplicate copies any creature on the board and gives that copy haste and soulbond — for four mana at instant speed, that's a combination of flexibility and immediate impact that most clone effects can't match. The ceiling is copying something like Kiki-Jiki, Mirror Breaker for an immediate combo trigger, and Sakashima of a Thousand Faces // Vial Smasher the Fierce makes it a staple by letting your copies stack without the legendary rule killing them.

14.4% of decks · synergy 0.13

Marchesa, the Black Rose wants creatures that can take damage, die, and return — Dack's Duplicate enters as a token, can attack immediately thanks to haste, and if it dies with a +1/+1 counter it comes back, generating repeated value from whatever it last copied.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern not legal
pioneer not legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Commander is where Dack's Duplicate actually lives — the format's singleton rule and multiplayer board states mean there's almost always something worth copying, and haste on a clone is a genuinely rare clause that enables combat and combo lines the turn it enters. In Legacy and Vintage it's legal but sees negligible play; those formats move too fast for a four-mana sorcery-speed effect to matter, and Clone effects don't compete with the raw efficiency of those environments. Oathbreaker is legal and occasionally relevant in creature-heavy pods, but the format's smaller life totals and faster games narrow the window. The card is, simply, a Commander card.
