SIEGE: World War II Deck Building and Supply Curve Guide

To build a reliable deck in SIEGE: World War II, balance low-cost screening infantry with targeted anti-tank units and tactical spells while targeting an average supply cost between 3.0 and 4.0. Because your supply bar regenerates at a fixed rate, an expensive deck prevents you from reacting to fast infantry rushes or cycling back to defensive answers.

Balance the Eight-Card Roster

Your eight-card battlegroup must handle both lane pushes and sudden counter-attacks without stalling your hand rotation. Incorporate cheap screening units to cycle cards quickly, back them up with heavy armor or anti-vehicle weapons, and reserve tactical spells to break enemy formations.

Keeping at least two low-cost response units, such as Riflemen or Scouts, ensures that an opening hand never leaves your bunkers exposed. Pair these with dedicated anti-armor options like Bazooka squads or stationary anti-vehicle emplacements so you are never forced to burn high-cost spells solely to stop a single tank.

Prioritize Frontline Troop Upgrades Over Spells

Because gold is limited during early and mid-tier progression, concentrate your currency on core combat units rather than spreading upgrades across your entire collection:

1. Upgrade primary infantry first: Units like standard Riflemen appear in almost every push. Leveling them up directly increases their health and damage, allowing them to win direct mirror engagements and maintain lane pressure.
2. Upgrade your primary vehicle: Tanks require sufficient durability to reach hostile bunkers and absorb defensive fire.
3. Delay tactical spell upgrades: Cards like Artillery Strike, Airstrike, and Smoke provide crowd control and utility regardless of level differences. An under-leveled spell still clears light swarms and disrupts lines, whereas an under-leveled infantry squad will quickly collapse against higher-tier units.

Reserve Tactical Spells for Defensive Swings

Avoid deploying expensive tactical cards proactively into empty lanes or against isolated scouts. High-impact spells provide the highest return when used reactively to create positive supply trades.

• Fight near your bunkers: Allow advancing enemy troops to enter the firing range of your stationary defenses before triggering damage spells. Bunker fire combined with an explosive strike wipes out supporting infantry cheaply.
• Neutralize armor with utility: Drop Smoke screens to blind incoming heavy tanks, allowing Bazooka squads or emplacements to eliminate the armored threat from outside its effective vision.
• Conserve reserves for counter-pushes: Spending high-cost artillery on a single low-threat unit drains your supply, leaving you vulnerable to an immediate push in the opposite lane.

Coordinate Armored Advances with Infantry Screens

Deploying a heavy tank alone at the bridge leaves it vulnerable to cheap counters. Tanks have slow rotation speeds and high deployment costs, making them easy targets for anti-tank infantry swarms and focused strikes.

Always spawn low-cost infantry slightly ahead of your armor. The screening troops absorb incoming anti-vehicle fire, trigger enemy landmines, and keep hostile anti-tank infantry occupied. This allows the tank's main gun to fire safely, forcing the opponent to spend excessive supply on defense and exposing their alternate lane to a secondary push.

Maximize Crates and Alliance Card Requests

Keep your card collection growing by managing crate unlock timers and leveraging alliance features daily:

• Stagger victory crates: Keep short-duration crates unlocking while actively playing, and start long-duration crates right before logging off.
• Target deck staples with requests: Join an active Alliance to request specific common and rare cards that fit your main deck, bypassing random drop pools.
• Donate surplus cards: Donate cards outside your primary battlegroup to alliance members to earn gold and account experience needed for expensive high-tier upgrades.
