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).

It wins less than its rating suggests.

Why this gap?

The pick rating is a prior: it is for choosing a card before there are results. The observed strength comes from real games, and the win rate of a card is stable from one week to the next. The gap often comes from a card that is easy to replace at the pick but very efficient once played, from a good archetype that carries it, or from a flaw of our rating: in a set that already has many games, the results are more reliable than the rating.

Good playable that always makes the cut (6.2/10).

Why. A variable-X sorcery: you reveal the top X cards, exile one per card type, put the rest in your graveyard, then put the exiled cards in your hand. If you exile four or more, you also cast one of the exiled spells for free.

Risks. To really pay off it needs a high cost and varied card types in your library. Cards put into the graveyard are lost if your deck gets nothing from them.

In the draft. A specialised card, weak in an ordinary deck. Only take it in a deliberately built graveyard deck; otherwise leave it.

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.

Card in hand at some point in the game52.8 %(set average : 56.0 %)

Card in the opening hand49.0 %(set average : 55.0 %)

Card drawn during the game55.0 %(set average : 56.6 %)

Gap when it is drawn, against the games where it is not : +2.8 win-rate points

Its place in the set

Rare: rank 46 of 60
Blue: rank 12 of 41
Cost 1: rank 14 of 30
Average pick: 7.8 (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.
