Underdark Basilisk turns any blocked combat into a one-sided board wipe — everything that blocks it dies, no combat damage required. The cost is a three-mana 2/3 that does nothing until it attacks, which makes it a liability in faster pods but a payoff card in any deck built to maximize deathtouch triggers, especially Fynn, the Fangbearer.

Commanders with the highest synergy
Fynn, the Fangbearer
Fynn, the Fangbearer converts each deathtouch creature that deals combat damage into a poison counter, and Underdark Basilisk's forced-block clause makes it nearly impossible for opponents to avoid taking that hit — trade their whole board or hand Fynn two poison counters either way.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | legal |
| standard | not legal |
| vintage | legal |
| pauper | legal |
| oathbreaker | legal |
In Commander, Underdark Basilisk earns its slot almost exclusively in deathtouch-matters builds — outside that lane, a 2/3 for three with no immediate impact is too slow for 100-card singleton. In Pauper it's legal but competes with cheaper deathtouch creatures that don't need to attack to generate value, so it rarely makes cuts. Legacy, Vintage, and Modern are non-starters for a vanilla-statted creature at this rate. Pioneer midrange has no reason to run it when the format offers far more efficient threats.

Price Context
Current price
$0.26 bulk tier
At $0.26, Underdark Basilisk is deep bulk — easy to pick up in any trade binder or as a throw-in. Bulk uncommons with narrow synergy profiles rarely move off this price floor unless a new commander pushes heavy deathtouch themes into the spotlight.
