How are these measures computed?
Pick rating. The pick rating estimates what a card is worth when you choose it, before there are results: it combines several signals (expert evaluations, the choices of strong players, characteristics of the card such as its cost and rarity) and was tuned on the results of decks of strong players. It is for comparing cards while you draft.
Observed strength. The observed strength is the win rate of the games in which the card was in hand at some point (opening hand or drawn), from hundreds of thousands of real games of online draft players since the set came out. The rank compares the cards seen in at least 1,000 games. It does not correct for the strength of the deck the card is played in, and a result stays uncertain for a card that is played little (about 1.6 points of margin at 1,000 games).
A solid playable that rarely gets cut (4.6/10).
Why. A two-power, four-toughness flier for four mana: a good defensive body and a decent aerial attacker. When you discard a card, you may exile it from your graveyard and play it until the end of your next turn.
Risks. Two power is modest, and the advantage needs discards, such as from connive effects. Without them she is mostly a 2/4 flier.
In the draft. A fair pick for black decks with discard or connive effects. Otherwise she is playable but unexciting.
Win rate of the card
Percentage of games won by the decks that play this card, depending on when it shows up, from the real games of the set.
Gap when it is drawn, against the games where it is not : +0.6 win-rate points
Its place in the set
- Uncommon: rank 74 of 100
- Black: rank 24 of 39
- Cost 4: rank 43 of 52
- Average pick: 8.1 (1 = taken first from a pack; the lower the number, the earlier players choose it)
Win rate by colour pair
Percentage of games won by the decks of each pair that play the card, with the number of games. The pairs are the two main colors of the deck: when the card has a color outside the pair, the deck plays it as a splash (marked “splash”). A pair that has an archetype in this set leads to its guide.
Win rate: strong players and all players
Percentage of games won when the card is in hand; strong players are those ranked diamond or mythic online.
