What players think

Bloomburrow is seen as a fairly fast, creature-based format with thin fixing (two-color decks are the norm) and removal coming mostly from white and black. Opinions split on archetypes: some put the Rabbits and Squirrels on top and the Birds and Otters at the bottom, while others champion the Mice , Frogs and Raccoons and find the Squirrels badly undercooked. Our measured games side with the former: the Lizards , Squirrels and Rabbits hold the top three spots, and and come last. The Mice and Raccoons only land in the middle of the ranking.

Mechanics of the set

• Offspring

  You may pay an additional cost as you cast the creature; if you did, when it enters, you create a 1/1 token copy of it.

• Gift

  As you cast the spell, you may promise an opponent a gift (a card, a Food token, a Treasure token or a tapped 1/1 Fish); they get it, and the spell usually has a stronger effect.

• Valiant

  An effect when the creature becomes the target of a spell or ability you control for the first time each turn.

• Threshold

  An effect that applies or triggers only if you have seven or more cards in your graveyard.

• Expend

  An effect when you spend your fourth total mana to cast spells during a turn (expend 4), or your eighth (expend 8).

• Forage

  To forage, you exile three cards from your graveyard or sacrifice a Food.

• Class

  An enchantment that levels up: paying a level's cost, at sorcery speed, adds its ability to the earlier ones.

The best cards

By colour

Rank by our rating, then rank by win rate when the card is in hand.

To remember

• Twenty-two cards have Gift: read each one, since the effect you gain differs; on Nocturnal Hunger, not giving costs you 2 life, and on Parting Gust, with no gift the creature comes back.
• Ten Class enchantments need mana and time to level up; ten Expend cards, on the other hand, want you to spend four mana on spells every turn.
• Each colour pair has its own gold uncommon "Mentor": it is the clearest signal of the open pair.
• The five "Village" lands give their colour only to cast creatures; for your other spells they only give colourless mana.
