Second Guess card art
Second Guess counters the second spell cast each turn for two mana — a narrow window that, in multiplayer Commander, opponents fill constantly. It's a cheap, real counterspell with a real restriction: if you can't reliably be holding up mana on an opponent's second spell, run Counterspell instead.

In Commander, Second Guess punches above its mana cost because four opponents means someone is almost always casting a second spell on their turn — tutors, cantrips, and ramp chains all trigger the window reliably. Legacy and Vintage have access to better unconditional countermagic, so Second Guess stays off most lists there; the format speed and density of broken first spells make the restriction genuinely punishing. Modern is technically legal but it sees no play — the format's tempo demands consistency that a conditional counter can't deliver. Second Guess is a Commander card first and foremost.

Price Context

Current price

$0.05 bulk tier

At $0.05, Second Guess is deep bulk — you'll find it in a common box before you'd bother ordering it. That price is stable by default; there's no trajectory up unless a Commander deck or precon suddenly features it prominently.
