November 12, 20261,726 words9 min read

Find the best Garden Tower Defense units for Classic, Endless, Survival, PvP, boss damage, AoE, stalling, and cheaper replacements.

The best Garden Tower Defense unit overall is Transfiguration Flower, according to the available October/November 2026 tier-list guide. Its attacks have a 5% chance to transform enemies into weaker versions, making it useful against regular waves and many bosses. Teslaflora, Infectia, Witchleaf, and Bunny Burrow are also among the strongest picks, but each serves a different role.

The source guide was updated for the September 26 update, listed as version 1.70.0, although the current version is not independently confirmed. See the full Garden Tower Defense unit tier list for the source rankings and reported stats.

Garden Tower Defense Unit Tier List

The guide places Transfiguration Flower in its highest listed tier. Other units are grouped below according to their reported usefulness, versatility, cost efficiency, and how difficult they are to replace.

Seedmill and Rangeleaf are especially valuable in full squads because their benefits become more noticeable when several teammates can use them. The guide describes F-tier units as outdated, making them better suited to collection purposes or trading rather than serious late-game lineups.

Best Overall Unit: Transfiguration Flower

Transfiguration Flower is the strongest general-purpose unit in the guide. Its passive gives each attack a 5% chance to turn an enemy into a weaker version. Its manual ability applies the same chance to every enemy within a 20-range area.

The transformation effect is particularly useful in long waves because it reduces the threat posed by tough enemies without relying only on raw DPS. The guide reports 4,834 maximum single-target DPS and lists Transfiguration Flower for Classic, Endless, and PvP.

Its main weakness is immune bosses. The source specifically notes that the transformation effect may fail against final enemies on Aqua and Volcano. The guide also reports a six-transformation limit per enemy, so adding several transformation units does not provide unlimited value.

Strongest Damage and Support Units

Teslaflora

Teslaflora attacks every enemy within its range. Its damage scales especially well with support from Festive Garden Warbell and Timekeeper. The source reports that Teslaflora can outgrow units with higher listed damage when it is fully buffed.

It is limited to two placements, so use those positions carefully. Teslaflora is one of the best choices for Survival, where boosted area damage can clear waves quickly.

Infectia

Infectia attacks once every 10 seconds, but its Contagious effect provides the main value. Poison damage remains on infected enemies, and the infection can spread to enemies within five range.

The guide lists Infectia as the best AoE unit, with 15,000 maximum DPS. Place it near the front of a path so early infected enemies have more time to spread the effect. Infectia is also the guide’s recommended unit for Endless mode, where gradual scaling and long-term damage matter more than fast opening-wave clears.

Bunny Burrow

Bunny Burrow is a spawner with infinite line range. Its recommended placement is toward the back of the map, where it can remain safe while producing value. The guide highlights it for Endless and Volcano, and reports 13,000 maximum DPS.

Bunny Burrow is useful when you want a lower-maintenance unit that can continue contributing while other units handle crowd control and support.

Festive Garden Warbell

Festive Garden Warbell is primarily a support unit rather than a damage dealer. Every four seconds, it grants nearby units a 1.8x damage boost for two seconds and adds a small area-of-effect stun. The guide estimates this averages to roughly a 1.4x damage multiplier over time.

Replacing one damage unit with Warbell can increase the team’s total output when several strong attackers are positioned nearby.

Timekeeper

Timekeeper provides a 20% attack-speed boost within its range. It can also revive the base after it falls, clear the map, and advance to the next wave. In Survival, the guide reports that it can revive the whole team after a complete defeat.

Its active ability stops time for four seconds and starts at a reported cost of $3,000 per use. Timekeeper is therefore less focused on maximum damage than Warbell, but its recovery tools provide additional safety during difficult runs.

Best Units by Game Mode

Mode	Recommended unit or core	Main priority
Classic	Transfiguration Flower	Fast clears and boss damage
Endless	Infectia	Scaling, poison, and stalling
Survival	Teslaflora, Timekeeper, Warbell	Buffed damage and recovery
PvP	Transfiguration Flower and Confusiflora	Transform effects and crowd control

Classic

Classic mode rewards speed. The guide recommends pairing Transfiguration Flower with Teslaflora, Warbell, Egg Basketstem, and Sentry Stem. Earth Dragon is also reported as useful on Dojo and Graveyard, while Clusterplant performs well on multi-lane maps such as Aqua and Back Garden.

Endless

Endless teams need damage that continues scaling as waves become harder. A strong reported core is Infectia, Transfiguration Flower, Confusiflora, Warbell, and Bunny Burrow. Viridian Branch can also fit into this setup because its damage reportedly increases by 20% every minute, up to an 80% bonus. Lullabloom provides additional stalling when waves become crowded.

Survival

The guide recommends Teslaflora, Timekeeper, Warbell, Witchleaf, and Seedmill for Survival. Earth Dragon is less effective here because its travel time reduces its value on long waves. Since balance changes can affect Survival picks heavily, these recommendations may change after future updates.

PvP

The source identifies Transfiguration Flower and Confusiflora as useful PvP choices. Transfiguration Flower can weaken enemies through transformation, while Confusiflora helps hold groups in place. The available material does not provide a complete PvP ranking.

Best Units by Role

Role	Best reported pick	Other options
AoE damage	Infectia, 15,000 maximum DPS	Bunny Burrow, Viridian Branch, Astraflora, Teslaflora
Boss damage	Voidanium, over 24,000 maximum DPS as Nullify ramps up	Bunny Mech, Ion Iris, Egg Plantinum
Stalling	Confusiflora	Auranji, Cryolesia, Confusion Plant
Damage support	Festive Garden Warbell	Timekeeper for attack speed and recovery
Poison synergy	Sentry Stem with a poison source	Egg Basketstem or Viridian Branch

Voidanium is identified as the strongest boss-damage option in the role comparison, although it does not appear in the main tier table supplied by the source. Bunny Mech is another strong boss choice, with a reported 16,875 maximum DPS and an Energy Blast that deals x50 damage. Ion Iris and Egg Plantinum are additional alternatives.

Sentry Stem deals 20% more damage to poisoned enemies. It should therefore be paired with a poison source rather than placed alone. Chicken Coop is effective against groups of mid-health enemies because its chicken damage is based on the weaker enemy’s maximum health, but the source notes that this damage is capped against very large bosses.

Best Replacements for Rare Units

You do not need every exclusive unit to build a competitive team. The guide recommends these lower-cost replacements:

Replace Transfiguration Flower with Witchleaf for another 5% transformation chance plus slowing.
Replace Confusiflora with Confusion Plant for group stalling.
Replace Egg Basketstem with Auranji for a reliable slow.
Replace Lullabloom with Jinx Plant as a cheaper stall option.
Replace Viridian Branch with Rangeleaf when you mainly need its range benefit.
Replace Festive Glowthorn with Blinkbloom for stronger early single-target damage.
Replace Teslaflora with Iced Prismflower for a reported alternative in many Classic runs.

Witchleaf shares the six-transformations-per-enemy limit with Transfiguration Flower, so using both repeatedly on the same target can waste placement space.

Common Team-Building Mistakes

Avoid stacking multiple effects that do not combine. The source reports that Shockolateflora’s 10% damage debuff and Lullabloom’s sleep debuff do not stack on the same target; only the stronger effect applies.

Do not fill every slot with transformation units. Once an enemy reaches the six-transformation limit, additional copies lose value. Similarly, Sentry Stem needs a poison source to activate its reported 20% damage bonus.

Finally, do not judge a unit only by trade price. Limited-stock exclusives can be expensive because they are scarce, while a cheaper unit may provide more practical value for a specific mode or role.

New Units to Watch

The source reports that Mortarfern and Chronorchid were added in the September 26 update but were not ranked yet because they needed more testing.

Mortarfern has unlimited range and lets players choose its firing location manually. Its shells deal area damage and leave acid puddles reported to deal 5,000 DPS. Chronorchid did not yet have enough reported testing for a reliable tier placement.
