Marsh Viper puts two poison counters on whatever it deals damage to — a meaningful rate in dedicated infect builds — but a 1/2 body for four mana is unacceptably slow for anything outside that specific context. Outside of poison strategies, it doesn't make the cut.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | legal |
| oathbreaker | legal |
Marsh Viper is legal in Commander, Legacy, Vintage, Pauper, and Oathbreaker, but relevance is a different question. In Commander, it sees fringe play in poison or infect-focused decks where stacking two counters per hit is the entire point — though faster, cheaper infect creatures almost always take priority. In Pauper, the format's low curve and efficient commons make a four-mana 1/2 with conditional upside a hard sell. Legacy and Vintage have zero interest in Marsh Viper at any price.

Price Context
Current price
$0.11 bulk tier
At $0.11, Marsh Viper is deep bulk — you're not paying for it, you're paying for the stamp. It won't appreciate; the supply is too large and the competitive demand is effectively zero.
