Tier List

Introduction

The All Star Tower Defense tier list ranks units by their overall strength across Story Mode, Infinite Mode, Infinity Tower, Raids and Tournaments. S-tier units are meta-defining carries that solo-carry content, while A-tier units are strong all-rounders that slot into almost any team. B-tier units work in specific compositions or against certain enemy types, and C-tier units are niche picks or early-game stepping stones. Tier placements change with every balance patch, so we keep this list current with the live meta and explain the reasoning behind each ranking. A high tier does not automatically mean a unit is right for your roster — star level, shiny variants and traits all affect real in-game performance. Use this list to prioritize which units to level, which banners to pull and which evolutions to chase.

Core Mechanics

Tier rankings in ASTD combine raw stats, attack type, range, star potential and evolution path. S-tier units usually have high base damage, excellent range or splash, and a strong evolution that scales into the endgame. Star level matters enormously: a 6-star or 7-star version of a B-tier unit can outperform a 4-star S-tier unit because star upgrades multiply base power. Shiny variants are cosmetic and do not change a unit's tier, but traits can shift effective strength — an S-tier unit with a bad trait loses ground to an A-tier unit with the All Star buff. The meta is mode-dependent: a unit that dominates Story Mode may fall off in Raids where boss damage matters more. Rankings also account for availability — hard-to-obtain limited units are powerful but may not be worth chasing if a comparable unit is easier to get.

Advantages

A well-maintained tier list saves you gems, time and frustration by telling you exactly which units are worth leveling. Instead of wasting resources on a visually cool but weak unit, you can focus your star upgrades, traits and evolution materials on proven carries. The tier list also guides your banner strategy — knowing which S-tier units exist helps you save gems for the right rotation instead of pulling randomly. For team building, the list groups units by role and mode so you can assemble a balanced squad that covers single-target damage, area damage and support. Finally, our tier list explains the reasoning behind every ranking, so you understand why a unit is strong rather than blindly trusting a letter.

Challenges

Tier lists become outdated fast in a game with frequent balance patches. A unit that is S-tier today can drop to A-tier after a nerf, and new units released every update can shift the meta overnight. Tier rankings are also somewhat subjective — different teams and different modes favor different units, so a letter grade cannot capture every use case. Availability matters: a top-tier limited unit you do not own is useless advice, and chasing it on a banner may cost far more gems than a slightly weaker but obtainable alternative. Finally, tier lists assume reasonable investment; an S-tier unit with no star upgrades or a bad trait will underperform a well-built lower-tier unit. Always combine tier advice with your actual roster and current patch notes.
