Aether Realms is a free fantasy trading card game played entirely in your browser — no download, no install. Pick one of ten kingdoms, each with its own fixed deck and strategy, and battle another player for control of the field.

Enter the Battle

Every match is a 1v1 duel: deploy units from your hand onto a battlefield of vanguard and rearguard rows, spend Mana to cast spells, and move to combat when you're ready to attack. Reduce the opponent's castle Health to zero before yours falls. See the full rundown on How to Play.

Choose Your Kingdom

Ten factions, ten philosophies of war — from board-wide aggression to a wall that never breaks. Every deck is ready to play immediately, no deckbuilding required to start.

Ten Factions. Ten Strategies.

From the Orc Horde's relentless aggression to the Dwarven Clans' unbreakable wall, no two kingdoms play the same. Browse every deck's full strategy, key mechanics, and strengths and weaknesses on the Decks & Factions page.

Master the Battlefield

Mana grows every turn, letting you deploy bigger threats as a match goes on. Attack Planning lets you queue several attacks and confirm them together with Attack All, instead of resolving each hit one at a time. A built-in guided tutorial teaches every mechanic hands-on — see How to Play for the full breakdown.

Build Your Deck

Every faction starts with a complete, ready-to-play deck. Once you own a faction, a full custom deck builder lets you build your own list from its card pool — no faction's identity is fixed once you've unlocked it.
