Cards are never bought and never unlocked: they are live from the very first login, for everyone. You win them in play, by hatching the wild egg.
Where cards come from
A wild egg drops onto your nest every 25 to 35 seconds. It slides like a creature but merges with nothing, and it vanishes if it sits 15 seconds without hatching.
To hatch it, block a creature against it. The card lands in your hand at once, and that hand holds at most 3 cards.
One tap plays a card, with no confirmation. The cards flagged below leave every hand during the last 30 seconds of the match.
Rarity is the card's weight in the egg draw: the nineteen weights share exactly one hundred points. The bigger the number, the more often the card shows up.
The attack cards
They hit your rivals and never you. Each one telegraphs itself before it lands, and a victim who takes one is immune to that same card for a few seconds.
Ink Splat
Effect
An ink blot covers a good third of the target nest. Not one creature moves: what gets hard is reading the board.

Scramble
Effect
Every creature in the target nest changes cell at once. None is lost and the score does not move: what collapses is the tidiness.

The collective cards
