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 uncommon of the format (7.2/10).

Why. A 1/3 that blocks small creatures well early and gives you one energy with each landfall. At six energy it taps to draw three cards: your lands turn into cards.

Risks. You need six lands for the first draw, and the next one takes six more. Once tapped to draw, it no longer blocks.

In the draft. A good blue pick for a control or midrange deck. It fits less in a very aggressive deck.

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 game58.4 %(set average : 56.2 %)
Card in the opening hand59.4 %(set average : 55.6 %)

Its place in the set

  • Uncommon: rank 9 of 120
  • Blue: rank 3 of 30
  • Cost 2: rank 16 of 86
  • Average pick: 4.9 (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.
