CORE STRATEGY: Build up your sites, flood as much of the realm as possible, and finish the opponent with heavy damage.

INITIAL SETUP/DRAW: Getting Island Leviathan one or multiple times (e.g. also thanks to Mirror Realm or later on via Selfsame Simulacrum) can help a lot in finishing the opponent quickly during the endgame. Alternatively, Floodplain (or later Flood / Atlantean Fate / Geyser / Great Old One) will allow flooding opponent sites consistently in order to remove their minions easily with Stormy Seas or Wrath Of The Sea (or Atlantean Fate).

SUPPORT (SPELLS): Anui Undine, Unland Angler, Diluvian Kraken and Great Old One are the heavy-hitter minions. Porcupine Pufferfish and Frog tokens (via Plague of Frogs and Tadpole Pool) will help with defense, Deep Sea Mermaids also defends and additionally supports card draw which achieved with Geyser and Riptide too. Riptide along with Marine Voyage (and Undertow) support movement of your avatar away from danger, Marine Voyage also accelerates movement of minions towards your opponent's avatar. Abundance and Aquamarine Core helps with mana ramp.

SUPPORT (SITES): River for mana and top/bottom decking cards for more predictable drawing. Maelstrom optionally moves minions away from your avatar or closer to each other (depending on situation). The rest is covered above.

MANA NEEDED: 8+
