Chaos Zero Nightmare: Rossweisse Carry Deck Compression Guide

To run an optimal Rossweisse carry team in Chaos Zero Nightmare, pair her with Magna and Adelheid while aggressively removing non-essential support cards. The objective is deck compression: eliminate basic strikes and low-value cards from your supports so your draw pile feeds Rossweisse high-impact offensive cards every turn, while Magna and Adelheid sustain the team using minimal Action Points (AP).

Core Strategy: Deck Compression for Rossweisse

Standard three-combatant compositions often struggle because support units draw basic attacks that consume hand space and starve your damage dealer of AP. This composition solves that issue by turning Magna and Adelheid into low-maintenance defenders.

Once early setup cards are played, exhausted, or retained, the active deck shrinks dramatically:

• Rossweisse acts as the sole offensive engine, spending the majority of team AP on high-scaling attacks and burst rotations.
• Magna provides front-line protection, holding enmity with taunts and absorbing incoming damage with heavy shields.
• Adelheid manages draw consistency and supplementary barriers, cycling through dead draws and lowering AP pressure.

With support card pools thinned down to essential defensive mechanics, your turn-by-turn card draw funnels directly into Rossweisse's primary damage sequence without compromising squad survival.

Support Role Breakdown and Card Priorities

Both supports must be built strictly for damage mitigation and hand cycling rather than damage output.

Magna's Defensive Focus

Magna exists to prevent lethal damage from reaching Rossweisse. Prioritize abilities that generate team shields or apply taunt to redirect single-target boss attacks. Cards carrying the Exhaust keyword are especially valuable: they deliver immediate protection during early rounds and permanently leave the draw cycle for the rest of combat, keeping future draws clean.

Adelheid's Utility Focus

Adelheid smooths out turn variance. Draft her around zero-cost utility, AP reduction, and draw manipulation. Her barrier skills stack on top of Magna’s physical shielding to handle unblockable or wide-area boss abilities. When your hand lacks immediate offensive follow-ups, Adelheid’s draw skills cycle the discard pile to return Rossweisse's burst cards into play immediately.

Card Selection and Thinning Rules

Building this composition requires disciplined deck curation during shop visits and run rewards.

Support Deck Management

1. Remove all basic strikes: Cut basic attack cards from both Magna and Adelheid at shops and event nodes as early as possible.
2. Prioritize Exhaust and Retain tags: Choose support skills that remove themselves from the cycle after use or remain held in hand until required.
3. Target a three-to-four recurring card limit: Aim for Magna and Adelheid to retain no more than three or four active cards each in the recurring deck rotation after the opening round.

Rossweisse Card Curation

• Protect combo chains: Retain high-scaling slashes, core combo enablers, and self-buffs while trimming low-impact filler.
• Draft high-cost finishers: Because Magna and Adelheid consume minimal AP after setup, Rossweisse can routinely cast high-cost damage cards without depleting the team's resource pool.

Combat Rotation

The opening turns establish your defensive perimeter, after which the rotation shifts entirely to carry output.

Turn 1: Defensive Setup

• Spend initial AP on Magna's taunt and exhaust-shield abilities.
• Deploy Adelheid's team buffs and draw-utility cards.
• Treat Rossweisse's damage as secondary during Turn 1; ensure your defensive barriers and enmity are fully active before spending AP on offense.

Turn 2 and Beyond: Carry Cycling

• With support cards exhausted or retained, draw hands will concentrate four to five Rossweisse cards per turn.
• Commit all available AP toward Rossweisse's offensive skills and finishers.
• Only cast cards from Magna or Adelheid when Magna's barrier breaks or an enemy telegraphs an unblockable party-wide attack.
