How to Mulligan Osgir, the Reconstructor

Mulligan decisions with Osgir, the Reconstructor start with role clarity: does your opener actually support a real Osgir, the Reconstructor game plan around artifacts and recursion? Artifact recursion deck that turns the graveyard into a second hand and copies key utility artifacts for burst value. Cheap artifacts that replace themselves are premium here because they keep Osgir's activation live without overcommitting. The best builds line up mana rocks, fodder artifacts, and a few high-impact targets to copy.

What a keepable hand looks like

In Commander, the London mulligan gives you a free first reset and rewards disciplined keeps. For Osgir, the Reconstructor, a strong opener usually does three things at once: develops mana, offers an early spell or piece of interaction, and points toward your actual game plan. Artifact recursion deck that turns the graveyard into a second hand and copies key utility artifacts for burst value. If your seven has lands but no way to advance that plan, treat it as shakier than it first looks.

Mana, colors, and early sequencing

Most Osgir, the Reconstructor decks still want the normal Commander baseline of two to four lands or a hand that clearly replaces missing lands with reliable ramp. Osgir, the Reconstructor is Boros, so your opener should cast your setup on time and not strand key colors in hand. Cheap artifacts that replace themselves are premium here because they keep Osgir's activation live without overcommitting. The best builds line up mana rocks, fodder artifacts, and a few high-impact targets to copy.

When to keep a borderline seven

If your list is built around artifacts, recursion, and graveyard, a borderline hand should still contain at least one card that matters for that package. Keep more aggressively when the hand has cheap setup plus enough mana to function. Ship more aggressively when it is all payoff, all air, or a pile of unrelated medium cards. Common misses include artifact bombs with no setup, too many nonartifact spells, and graveyard plans without self-stock or sacrifice support.

Play vs draw

On the draw, the extra card gives Osgir, the Reconstructor more room to keep a slower hand, especially one with two mana sources and a real early spell. On the play, be tougher on reactive hands that do nothing proactive until turn three. If your build is faster or more controlling than average, compare both modes in the simulator so your mulligan habits match the exact list you are piloting.
