🤝 Co-op Team Composition Tier List: Best 2/3/4-Player Combos
📅 Updated Jun 3, 2026 · ⏱️ 13 min read · 🏷️ Tier List Co-op
Post-Devour the Tower, the co-op meta has crystallized. 34 streamers ran 17 team comps through 48+ hours of high-stakes co-op. These are the team compositions that work — ranked by community consensus and tournament results.
The Four Co-op Roles
| Role | Primary Job | Best Characters |
|---|
| 🛡️ Tank | Absorb shared damage, generate party block | Ironclad, Defect (Frost) |
| ⚔️ DPS | Burst damage, boss killing | Silent, Necrobinder |
| 🔮 Support | Buff party, debuff enemies, enable combos | Regent, Silent |
| 🔄 Flex | Adapt to what the team needs | Defect, Ironclad |
2-Player (Duo) Tier List
S-Tier Duos
| Duo | Synergy | Tournament WR |
|---|
| S Silent (Sly Discard) + Necrobinder (Summon) | Silent debuffs enemies → Necro minions pick off weakened targets. Shared enemy debuffs in co-op. Necro minions can body-block for Silent's fragility. | 41.2% (Devour the Tower winners) |
| S Ironclad (Exhaust) + Silent (Sly Discard) | Ironclad tanks shared damage, Silent deals damage + controls. Corruption + After Image provides infinite block for the party. | 38.7% |
| S Defect (Frost Wall) + Regent (Starfall) | Defect provides party-wide block via Frost orbs. Regent spends Stars uninterrupted. Unkillable + unstoppable. | 36.5% |
A-Tier Duos
| Duo | Synergy |
|---|
| A Silent (Poison) + Necrobinder (Doom) | Double HP-scaling damage. Both bypass block. Bosses die in 3 turns. |
| A Ironclad (Strength) + Defect (Frost) | Defect blocks, Ironclad smashes. Classic carry-support dynamic. Safe but slow. |
| A Regent (Sly Control) + Silent (Sly Discard) | Double Sly synergy! Shared Sly buffs, infinite card draw, enemy debuff stacking. Requires coordination. |
B-Tier Duos (Viable but Suboptimal)
| Duo | Weakness |
|---|
| Ironclad + Regent | No shared damage type synergy. Ironclad wants to tank, Regent wants to scale — they don't help each other. |
| Defect + Necrobinder | Both want to set up. Too slow — elites punish you before either character comes online. |
| Silent + Silent | Mirror comp. One Silent will get contested on Sly/Discard cards. Food chain problem in shared card pools. |
3-Player Team Comps (Ranked)
| Rank | Team | Roles | Why |
|---|
| S | Silent + Necrobinder + Ironclad | DPS + DPS/Tank + Tank | Tournament-winning comp. Silent debuffs + Necro minions + Ironclad party block covers everything. |
| A | Defect + Silent + Regent | Tank + DPS + Support | Frost block + Sly control + Star burst. Three distinct roles, no overlap. |
| B | Ironclad + Defect + Necrobinder | Tank + Flex + DPS | Two tanks is wasteful. Drop Ironclad for Silent. |
4-Player Full Team (Ranked)
| Rank | Team | Why |
|---|
| S | Silent + Necrobinder + Defect + Ironclad | Covers all 4 roles perfectly. Silent DPS + Necro off-DPS + Defect block + Ironclad front-line. Redundancy in damage and block. |
| A | Silent + Necrobinder + Regent + Defect | More complex but higher ceiling. Regent enables Silent and Necro to go full aggro while Defect walls. |
| B | Ironclad + Regent + Defect + Silent | Balanced but unfocused. No clear DPS carry — damage is spread thin. |
Co-op Drafting Rules
- Avoid overlapping same-color cards: Two Defects contest Focus cards. Two Silents contest Sly cards. The shared card pool is zero-sum.
- One tank minimum: Shared damage in co-op means someone MUST absorb hits. Ironclad or Frost Defect are mandatory in 3+ player teams.
- Spell-based synergy: Cards that affect "all enemies" or "all allies" have multiplied value in co-op. Electrodynamics, Corruption, After Image.
- Communication beats tier lists: A well-coordinated B-tier duo beats a silent S-tier duo every time. Discuss turn order, buff timing, and target priority.
🎯 Key Takeaway: Silent + Necrobinder is the undisputed king of 2-player co-op (41.2% tournament WR). For 4-player, Silent/Necrobinder/Defect/Ironclad covers every role without card pool conflicts. The #1 co-op mistake is double-dipping on the same character's card pool.
