6 Amphitrite
Sea-Crowned Queen
Arrival: Summon 2 Nereids.
“The deep does not send its queen alone.”
She refused Poseidon twice and was fetched back by a dolphin the third time. The Nereids who attend her have never once been dismissed.
Warden of the Deep Tide
Poseidon
“Even mountains remember the sea.”
Board tempo and alternating tides 
Power: Tidal Call

At Low Tide, summon a 1/2 Nereid with Guard. At High Tide, give a friendly unit +1/+1 permanently.
Low Tide defends, High Tide grows. Plan the turn the tide turns.
Mechanic: Tide
Start at Low Tide. At the start of each of your turns after the first, the Tide turns. Cards marked Low Tide or High Tide use only the clause that matches the current Tide.
- Strength
- Resilient boards, defensive summons, alternating aggression and protection.
- Weakness
- Needs units to exploit buffs; returning enemies does not permanently remove them.

6 
8 Charybdis
The Swallowing Throat
Arrival: Destroy all enemy units with 3 or less maximum Health.
“Three times a day I am hungry. Plan the crossing.”
She drinks the strait down to its stones and gives it back again, and nothing small that was floating on it comes back with the water. The few who cross her twice describe only the noise.
7 The Ninth Wave
In one batch, deal damage to the enemy hero and to every enemy unit equal to the number of friendly units you control.
“Count my ships. That is the number.”
Sailors number the waves and dread the ninth, which comes in higher than the eight that taught them what to expect. Poseidon has never denied choosing it deliberately.
7 Nereus
Elder of the Salt Deep
Guard. At the start of your turn, restore 2 Health to all friendly characters.
“Fifty daughters and no patience. Ask quickly.”
The old man of the sea answers truthfully to anyone who can hold on to him, and the list of those who managed it is short. His daughters come up the beach behind him without being called.
7 Triton
Herald of the Depths
Arrival: Low Tide — Give your other units +0/+2. High Tide — Give them +2 Attack this turn instead.
“Hear the conch. Know what follows.”
His conch can calm a sea or raise one, and he has never explained how he chooses. The fleets simply listen and act.
4 Skyphios
First Out of the Stone
Onslaught. After this attacks, return this unit to your hand.
“Hold the reins loosely. I am only lent.”
Poseidon drove his trident into a Thessalian hillside and the first horse came out of the split, still wet. No stable built since has held him past a single evening.
The Dawn We Owe
Poseidon’s road to Eidra
Surf breaks behind Poseidon’s sea-worn throne on the Aegean coast, and the sunset gilds its columns.
The harbor will not empty: every ship that reaches the outer water is folded back to the same quay.
