Team building
Build a six-slot roster by coverage, economy, damage, support, and stage mechanic—then substitute the strongest units you actually own.
A team must answer the map's target types before it optimizes damage.
Placement and upgrade cost decide whether your theoretical carry ever comes online.
If two units do the same job, make sure the duplication is intentional.
Four foundations
Examples name roles rather than pretending every player owns the same limited units.
Use this when you do not know the map yet. It minimizes auto-losses to coverage and economy mistakes.
Accept a slower opening only when the map gives enough time for farm and scaling units to repay their slots.
A current raid mechanic can be more important than the global tier list. Replace the flex slot first.
Read restrictions before locking the team; traitless or element rules can invalidate an otherwise premium roster.
Substitution rules
| Missing role | Look for | Avoid |
|---|---|---|
| Early defense | Low placement cost, quick useful upgrades, reliable area coverage | A slow scaler that consumes all starting cash |
| Flying coverage | Hill or hybrid targeting with a practical attack pattern | Assuming a ground-only S unit can hit everything |
| Economy | Farm value that repays before the stage ends | Farm in a short stage where it never breaks even |
| Support | A buff that benefits several core units at once | Building around a narrow buff with no compatible carry |
| Boss damage | True damage, boss multiplier, summons, or long-fight scaling | Judging only by wave-clear AoE |
Use the unit profiles for tradeoffs, then check the mode-specific priority before spending resources.
