At A Glance
- Discover the strongest units currently dominating the meta.
- Learn which units deserve your upgrade resources.
- Build stronger attack and defense teams with better unit synergy.
If you’re wondering which units you should invest in first, this Castle Busters tier list is designed to help. Since resources can be limited—especially for free-to-play players—choosing the right units early can significantly improve your progression.
While balance changes may shift the rankings over time, these units consistently perform well across PvP battles and castle assaults.
S-Tier Units
Bomber
The Bomber excels at dealing massive structural damage. Since destroying enemy castles is the primary objective, few units provide as much value.
- Exceptional castle damage
- Excellent during late-game pushes
- Forces opponents to react immediately
Knight
The Knight offers one of the best combinations of durability and damage.
- High health pool
- Reliable frontline tank
- Excellent for protecting ranged units
Nearly every competitive deck benefits from including a strong frontline tank.
Archer
Archers provide consistent ranged damage while staying safely behind your tanks.
- Long attack range
- Strong sustained DPS
- Excellent support unit
Positioning matters, but skilled players can get tremendous value from Archers.
A-Tier Units
Wizard
The Wizard deals splash damage that clears grouped enemies quickly.
- Swarms
- Defensive formations
- Clustered castle defenses
Spearman
Spearmen are inexpensive to deploy and offer strong value for their cost.
- Fast deployment
- Good reach
- Great early-game pressure
Cannon Crew
Although vulnerable to fast attackers, Cannon Crew can melt enemy defenses if protected properly.
B-Tier Units
These units remain useful but often require stronger team compositions.
- Swordsman
- Crossbow Soldier
- Shield Guard
They are reliable replacements until stronger options become available.
C-Tier Units
These units aren’t necessarily bad, but they are generally outperformed by other choices.
- Poor damage output
- Weak survivability
- Limited usefulness in higher arenas
If you’ve already upgraded them significantly, they can still contribute, but they shouldn’t be long-term priorities.
Best Team Combinations
Rather than focusing only on individual rankings, think about synergy.
- One frontline tank
- One or two ranged damage dealers
- One castle-destroying specialist
- One flexible utility unit
This composition works well across most game modes.
Upgrade Priority
- Primary damage dealer
- Frontline tank
- Castle-destroying unit
- Support units
- Situational units
Avoid spreading upgrades across too many characters.
Should You Follow Every Tier List?
Not necessarily. The best players often win because they understand positioning, timing, and castle management rather than simply using the highest-ranked units.
If a particular unit fits your preferred strategy, it’s perfectly reasonable to invest in it—even if it ranks slightly lower.
Final Thoughts
A strong Castle Busters deck starts with smart investments. Prioritizing powerful units like Bomber, Knight, and Archer will make progression significantly easier while helping you climb PvP rankings.
Remember that balance updates can change the meta, so revisit your upgrade priorities whenever new patches are released. Strong teamwork between your units will almost always outperform simply using individually powerful characters.
