Once cast, 50% of this card is still on the battlefield at game end. This reflects how often it survives removal, not just whether it's a permanent.

≥ -5.6pp

Players who cast this card win 30% of the time (n=19) , vs 14% when it never left the library (n=101).

When players drew this card but left it in hand, they won 19% (n=18).

Read this as correlation, not as the card's contribution. Casting a card means you lived long enough to cast it, so this gap widens with mana value across every card we track.

Observed gap +16.4pp; 95% confidence interval -5.6pp to +38.4pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Arvinox, the Mind Flail

{4} {B} {B} {B}
Legendary Enchantment Creature — Horror
Arvinox isn't a creature unless you control three or more permanents you don't own. At the beginning of your end step, exile the bottom card of each opponent's library face down. For as long as those cards remain exiled, you may look at them, you may cast permanent spells from among them, and you may spend mana as though it were mana of any color to cast those spells.

Frequently Asked

Why isn't there more data on this card?
Playgroup Live collects per-card gameplay data from real Commander games. Play counts appear once a card reaches 100 tracked games, and the full charts need a sample of at least 25 observed games that is not dominated by a single pilot. Until this card clears those bars you're seeing only the basic counts. Stats refresh nightly.
How is Playgroup Live card data collected?
Players using Playgroup Live import their decklists before a game and log card actions as they play. Each cast, zone change, and resolution is recorded as a real game event. Stats on this site are computed from those events, not from decklist scrapes or theorycrafting. Playgroup has recorded 690,000+ Commander games overall, and this card-level play data comes from the Playgroup Live subset of that corpus.
