Floodline Legion

Build a deck. Summon an army. Win the battle. Your deck is your army — and every card is played in real time. Floodline Legion blends two genres that rarely meet — the deckbuilding roguelite and the real-time autobattler. Every card in your hand is a soldier waiting to enter the fight. Drop a unit onto the single lane, and it advances, clashes, and falls on its own. But when to summon, what to save your mana for, and how to turn your deck into a snowballing army are entirely up to you. Mana builds continuously, and cards trickle into your hand a few at a time. Every moment asks a small question — spend now to hold the line, or save for the card that can end the fight? Forge a build, not just a deck Within the Human faction, three archetypes pull your deck in different directions — and the strongest runs weave them together: - The Swarm — cheap conscripts arrive several at a time, supported by banners and war horns that strengthen every ally based on your growing Host. Pack the lane wall-to-wall with bodies. - The Blessing — slow to start, terrifying once it gets going. Stack permanent buffs across your entire army, then field elite units that scale with those stats. A single blessed unit can clear the screen by itself. - The Contagion — death is contagious. Venom ignores defense, grinds enemies down over time, and spreads to nearby enemies when its host dies. Hold the line long enough, and the enemy army collapses on its own. These archetypes do not exist in isolation — they naturally connect through cards, keywords, and the engraving system. Cards, keywords, and engravings that bend the rules Units are not the only things fighting. Some cards and engravings rewrite the very rules of battle. - Keywords — over twenty keywords and status effects each add their own tactical twist. For example, Rear and Front make unit placement matter even on a one-dimensional frontline. Charge grows stronger the longer you hold it in hand, and Venom spreads when its host dies. Every keyword opens up a new line of play. - Engravings — permanent upgrades etched onto individual cards. Variant engravings go even further, transforming a unit into a different archetype. An ordinary Mage can become a Blessing Mage, a Venom Mage, or a Host Mage. Mix and match variants to build something far stronger. - Rule-bending cards — build your deck and summon your army from over 60 cards. Some cards do more than add power — they change the shape of the battle. The Rewind card sends only the enemy back to the start of the previous round, while your army stays exactly where it is. Buy time, build a powerful formation, and turn a single card into a complete reversal.
