Overview

This Fuse tier list ranks each Fuse by competitive viability and discusses each Fuse's strengths and weaknesses.

We understand that the team pairing greatly influences a Fuse's strength. However, even with just the 11 champions available in Early Access, there are already 55 unique teams of two.

These rankings reflect overall competitive viability, and take into consideration the strength of champs that synergize best with each Fuse, as well as average assessment of how much benefit each Fuse's unique power offers to a team.

Highest Ceiling

Freestyle

At the top, we are putting Freestyle Fuse for it's versatility and unmatched capability to break through the opponents defense.

The primary use for Assist's in 2XKO is to cover your approach in neutral, increase block pressure, and convert combos. Freestyle allows you to do all of these at a higher average level than any other Fuse.

At the highest level of play, players have solid defense, and landing a hit that you can convert into meaningful damage is your #1 concern. Being able to add an entire extra layer of mixups from a 2nd HandshakeTag makes successfully defending significantly more difficult.

Additionally, Freestyle's 2nd HSTag can be used for combo extensions for extra damage when you don't need use your assist to open up the opponent.

In tournaments and pro-play, you'll see multiple players running Freestyle teams in every top 8.

The only real downside of Freestyle, is that it's peak damage from an individual combo is generally lower than Double Down, but for most teams, the benefits outweigh the consequences.

Easier to Execute

2X Assist

When you are piloting champs that have outstanding assists like Illaoi or Warwick, 2X Assist can take your team from good, to oppressive.

Anytime you call assist, the opponent has be cautious of getting caught by the second attack. This gives you a nice window of time with added pressure, where you can take advantage of the other player's hesitation.

If they decide to keep up the aggression anyway, you can often get the punish with your second assist.

2X Assist also greatly extends your Point champs block pressure and enables them to repeatedly mix up the defending opponent before the opponent has a chance to counterattack. Having two assists leaves very few openings in your offensive pressure.

Considering how vital keeping or taking your turn is in competitive play, it's no mystery as to why 2X Assist is such a strong Fuse.

Double Down

Of the main 3 Fuses, Double Down is likely the most team-specific Fuse.

Although not every champ has good synergy with the Double Down Super combos and SuperTag, the ones that do make it look like the most busted mechanic in 2XKO.

If you've watched any pro-level Teemo+ Ahri team use Double Down, then you know exactly what we are talking about. They can dump two Supers each in one combo for a four Super combo, resulting in extremely high damage.

Tournament matches can be decided by a single successful hit that converts into a big Double Down Super combo.

SuperTag is also very effective at creating block pressure and mixup opportunities, similar to Freestyle and 2X Assist. The only downside is that the Fuse is entirely dependent on Super meter resource.

Mostly For Learning

Juggernaut and Sidekick

The two Fuses that share the similarity of being limited to a single Point champ have not seen any notable competitive success at this moment. That being said, there are sightings of players using these still, even at Diamond through Grandmaster.

Juggernaut and Sidekick are purposely balanced to avoid being extremely overpowered, making it easier for newer players to pick up 2XKO. Learning how to pilot a single character instead of two characters is literally half the work.

Because you have access to assists, Sidekick is better for transitioning to one of the three main Fuses.

Juggernaut has the mega benefit of having immediate access to Fury, and every champ has touch of death Fury combos. Even though neither of these Fuses has had much presence in high-level play, it doesn't mean that they aren't still decently strong.

We've seen players climb to GM with only using Juggernaut or Sidekick, so the takeaway here is not that they are too weak to use. Only when compared to the top 3 Fuses, there are notable weaknesses to limiting yourself to a single point champ.
