 Six rounds, each with its own shop tier deck. Per round:
 
-1. **Shop** — each player has 3 coins and players alternate actions, 1 coin
-   each: **buy** one of 4 face-up cards; **discard** any number of hand cards
-   (each becomes an 🍎 apple, +1 power food); or **trade in** 3 same-suit pets
-   to pick 1 of the top 2 cards of the next tier's deck (the other goes under
-   that deck). Passing forfeits remaining coins.
-2. **Cleanup** — anyone holding more than 5 pets must discard down to 5
-   (discards become apples).
-3. **Arrange** — players secretly order their decks. Food cards apply to the
-   next pet after them; trailing foods are wasted.
-4. **Battle** — automatic. Front pets simultaneously deal their full power to
-   each other as damage markers; a pet with markers ≥ power dies (attack
-   power never drops while wounded). Last player with pets standing wins the
-   round: 1 trophy for rounds 1–5, 2 trophies for round 6. Draws award
-   nothing.
+1. **Shop** — each player has 3 gold and players alternate actions, 1 gold
+   each: **buy** one of 4 face-up cards; **sell** any number of hand cards
+   (each becomes an 🍎 apple, +1 power food, and Sell effects fire); or
+   **trade in** 3 same-suit pets (the Triple action) to pick 1 of the top 2
+   cards of the next tier's deck — Triple effects fire on the traded cards
+   and the received pet's Buy effect fires. Passing forfeits remaining gold.
+2. **Cleanup** — anyone holding more than 5 pets must sell down to 5.
+3. **Arrange** — Battle Prep effects fire first (e.g. Giraffe hands out
+   apples), then players secretly order their decks. Food cards apply to the
+   next pet after them; trailing foods are wasted. A pet only benefits from
+   its last-applied **perk** (e.g. Honey, Garlic).
+4. **Battle** — automatic stack machine. Cards reveal off the top of each
+   deck until a pet is in play. Play effects fire on reveal (rocks roll a d6
+   with faces 0/0/1/1/2/2 and hit the opposing pet before the clash). The two
+   pets simultaneously deal their full power to each other as damage markers;
+   a pet with markers ≥ power faints (attack never drops while wounded).
+   Faint effects can push cards (apples, bees) onto either deck, recycle a
+   pet's apples (Dodo), or set aside delayed rocks that hit BOTH active pets
+   (Badger); survivors that took damage fire Hurt effects. Garlic prevents 1
+   damage from every attack that hits its pet — a clash that damages no one
+   ends the battle as a stalemate draw. Last player able to field a pet
+   wins: 1 trophy for rounds 1–5, 2 for round 6. Draws award nothing.
 
-Most trophies after round 6 wins. Pet effects are not yet implemented (the
-card model carries an `effect` field for when they land).
+Apples and bees are **temporary**: they leave your deck after the battle.
+Most trophies after round 6 wins.
+
+Tiers 1–3 use real card data (T1: Ant, Cricket, Duck, Otter, Mosquito, Fish;
+T2: Worm, Flamingo, Peacock, Swan, Rat, Spider + Honey; T3: Dog, Dolphin,
+Giraffe, Camel, Sheep, Dodo, Badger + Garlic). Tiers 4–6 are effect-less
+placeholders awaiting their real definitions.
