Space Groove is one of the more rewarding vertical traits in TFT Set 17: Space Gods. You only need a single Space Groovian on your board to unlock the trait, but the real power spikes happen as you stack more of them. The composition runs 7 champions across a wide range of gold costs, which gives you a clear early-to-late game progression path with Blitzcrank as the crown jewel at 5 gold.
How does Space Groove work in TFT Set 17?
The core mechanic revolves around a state called "the Groove." When a Space Groovian enters the Groove during combat, they gain attack speed and max health regeneration, and both values scale up as you add more Groovians to your team.
According to Mobalytics' Set 17 guide by Silverfuse, the trait breakpoints work like this:
The 5-unit breakpoint is where the trait becomes genuinely threatening. That 3% stacking Attack Damage and Ability Power per second means fights that drag on favor you heavily, especially when your frontline is buying time for carries like Nami and Blitzcrank to ramp up.

Even running a single Space Groovian gives your team the Groove entry mechanic. If you pick up a Teemo or Nasus early and have no other direction, they still contribute something rather than sitting idle.What secondary traits do Space Groove champions bring?
One of the strengths of running a full vertical trait is the web of secondary synergies you activate along the way. Space Groove's 7 champions cover a solid spread:
- Teemo (1g): Shepherd
- Nasus (1g): Vanguard
- Gwen (2g): Rogue
- Ornn (3g): Bastion
- Samira (3g): Sniper
- Nami (4g): Replicator
- Blitzcrank (5g): Party Animal + Vanguard
The most notable natural pairing is Vanguard, which both Nasus and Blitzcrank share. That gives you a built-in frontline synergy without needing to splash extra units. Bastion on Ornn and Rogue on Gwen add further defensive and damage layers depending on how your augment and item situation shapes up.
info
Blitzcrank holds the rare distinction of carrying two secondary traits: Party Animal and Vanguard. That double-dipping makes him exceptionally efficient as a 5-cost anchor for the board.
All 7 Space Groove champions explained
Teemo (1g) - Shepherd
Teemo is your cheapest entry point into the trait. His ability, Double Time, has both a passive and an active component. Passively, his attacks deal on-hit magic damage and apply a poison that deals additional magic damage over time (both scaling with AP). Actively, he gains a burst of attack speed for a set number of attacks. While an enemy has Groove Stacks, Teemo counts as being in the Groove himself, which keeps his passive ticking.
At 1 gold he is easy to three-star early and serves as a reliable damage-over-time unit in the opening stages.
Nasus (1g) - Vanguard
Nasus is the early-game tank. His ability, Goovin' Susan, transforms him for several seconds, temporarily granting bonus max health and dealing magic damage to adjacent enemies each second (scaling with both Health and AP). While transformed, Nasus enters the Groove.
He pairs naturally with Blitzcrank since both hold Vanguard. The important thing to keep in mind: Nasus is a placeholder tank. His items need to move to a stronger frontline unit as you approach the late game. Holding onto him with tank items past mid-game is a common mistake.
Gwen (2g) - Rogue
Gwen brings Rogue damage amplification and her ability Dance n' Dice. Passively, she deals magic damage. She enters the Groove while targeting an enemy below a certain health threshold. Her active has her dash to a nearby hex and snip the lowest percent-health enemy, dealing magic damage to the target and cone damage to surrounding enemies. If the target dies, she resets and dashes again at reduced damage.
At 2 gold with a reset mechanic, she should be a strong carry option through the early and mid game before Nami and Blitzcrank come online.
Ornn (3g) - Bastion
Ornn is the composition's primary mid-to-late game tank option. His ability, Disco Inferno, has a passive that forges a temporary completed item at combat start. If Ornn already has 3 items equipped, a random one becomes Radiant for the rest of that fight. His active grants him an AP-scaling shield for a duration, followed by a cone of fire dealing magic damage. Once any shield on him expires, Ornn enters the Groove.
That passive is the standout mechanic here. Because you have some influence over which item becomes Radiant based on what you build on Ornn, you can set up consistent Radiant procs on the items that matter most. That makes item selection on Ornn a genuine decision point rather than an afterthought.
warning
If Ornn already has 3 items equipped when his passive triggers, the Radiant upgrade is random among those items. Plan your Ornn itemization carefully so the randomness still lands on something useful.
Samira (3g) - Sniper
Samira is a Sniper with the ability Jump and Jive. Her passive fires a shot at any enemy that gets knocked up, dealing physical damage (scaling with AD and AP) and putting Samira into the Groove for several seconds. Her active builds on that same knock-up theme.
This has a lot of potential with the right augments. As Silverfuse notes in the source guide, there are echoes of previous sets where knock-up-focused compositions created some genuinely chaotic and effective boards. Samira's passive makes her naturally stronger in comps that layer crowd control, so keep an eye on what Blitzcrank's knock-up can set up for her.
Nami (4g) - Replicator
Nami is a 4-cost carry. Her Replicator trait lets her repeat her ability, Bubble Pop. She tosses a disco bubble at her target that splits magic damage across enemies in a 1-hex radius. The explosion then sends projectile globs toward nearby enemies, each dealing additional magic damage. Casting puts Nami into the Groove for several seconds.
The honest concern with Nami, as noted in the source material, is her limited target coverage per cast. She needs the frontline to chew through enemies before she can access the backline with Bubble Pop. Proper positioning and a durable frontline are non-negotiable if you want her to perform.
Blitzcrank (5g) - Party Animal + Vanguard
Blitzcrank is the late-game anchor. His ability, Party Crasher, calls down a lightning bolt on the highest-health nearby enemy every few seconds (passive), dealing magic damage. His active summons a disco ball at the largest enemy cluster, then uppercuts his current target for magic damage, knocking them into the disco ball for an explosion that deals magic damage in a 3-hex radius. The duration he spends in the Groove scales with how many enemies the explosion hits.
Crowd control, area damage, and Groove entry all in one package. He is the reason this composition trends toward a fast-8 strategy: the payoff for finding Blitzcrank early at 5-star or three-star is enormous.
How should you build toward Space Groove?
The natural game plan is a tempo start into fast-8. You have two solid 1-cost units in Teemo and Nasus to stabilize early, Gwen as a 2-cost carry bridge, and Ornn as your first real power spike at 3 cost. From there, the goal is to hit level 8 as efficiently as possible to find Nami and Blitzcrank.
Item priority should reflect this progression:
- Tank items on Nasus early, with a plan to transfer them to Ornn or Blitzcrank later.
- Carry items on Gwen through mid game, then shift to Nami once she comes online.
- AP-focused items generally benefit the most champions in this composition given how many abilities scale with AP.
The Vanguard synergy between Nasus and Blitzcrank is free, so you get frontline durability without dedicating extra board slots. Ornn's Radiant passive adds a layer of item scaling that most other 3-costs simply cannot match.

When building Ornn's items, think about which one you would most want to go Radiant. Building toward that outcome is one of the few ways to influence an otherwise random proc.
