Slithermuse enters and forces each opponent with more cards than you to match your hand size — in a four-player pod, that's potentially a massive one-sided refill. The cost is a five-mana 3/3 body with no evasion, so you're paying for the trigger, not the creature; Ashling, the Limitless decks happily pay that price because they're already copying enter-the-battlefield effects and multiplying the draw.

Ashling, the Limitless
Ashling, the Limitless copies Slithermuse's triggered ability each time it enters, which means a single cast can strip opponents down to your hand size multiple times over — turning what's normally a one-shot refill into a repeatable hand-size leveler that scales with however many copies Ashling generates.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Commander is where Slithermuse actually earns its slot — three opponents running full hands means the trigger routinely draws four to eight cards in a single cast, a payoff no 60-card format can match. In Legacy and Vintage it's a fringe option at best; the five-mana cost is punishing in formats where the game often ends on turn two or three, and opponents rarely hold enough cards to make the effect worthwhile. Modern is legal but practically irrelevant — faster clocks and leaner draw spells crowd Slithermuse out entirely. Stick to Commander, where the multiplayer math and slower pace let it do what it was designed to do.

Price Context
Current price
$0.72 bulk tier
At $0.72, Slithermuse sits firmly in bulk territory despite being a genuine draw engine in the right shell. The price reflects narrow demand — it's a Commander-specific card with a ceiling tied to how many Ashling, the Limitless and similar ETB-copy decks exist — so don't expect it to climb, but at under a dollar it's an easy include if the synergy is there.
