Riftbound's fifth set Radiance has arrived with a musically-inspired theme and three new mechanics poised to disrupt the competitive meta. I went hands-on with the cards at an early Pre-Rift tournament and sat down with executive producer Chengran Chai to understand how Disarm, Show Off, and Deploy will reshape the League of Legends TCG.
Deploy and Disarm specifically target defensive playstyles, forcing opponents to reconsider how they protect battlefields.
New Radiance Keywords: Disarm, Show Off, Deploy
Disarm is the most straightforward of the three new mechanics. When a unit with Disarm attacks, it reduces the Might of an enemy unit at that battlefield by one. The green Calm unit Ahri, Confident comes with Disarm built in and gains +1 Might whenever she reduces an enemy's Might, creating a snowball effect that rewards aggressive positioning. The blue Mind unit Kai'sa, Rebel pairs Disarm with a utility effect: she gives spells Reaction speed during showdowns, letting you respond to combat tricks at instant speed.
Show Off introduces a risk-reward layer familiar to veterans of other TCGs. Cards with Show Off grant an additional effect if you reveal a qualifying card from your hand to your opponent as you play it. We've only seen four cards in Radiance with Show Off so far–two units and two spells–and they each grant totally different effects. The yellow Order spell Rousing Display, clearly designed for the Seraphine Legend, plays four 1-Might Recruit Tokens to your base instead of one if you Show Off a card with Energy cost 7 or higher. Chai explained the trade-off:
"If I'm planning a spell heavy deck, whether you have Defy or not in your hand matters a great deal to me. Show Off basically opens up another dimension to the kind of like, 3D, 4D chess — that's 5D."
Chengran Chai, Executive Producer
Maybe you show your opponent something you have on purpose to throw them off, pushing them into a play you have the perfect counter-play for. Show Off has the possibility of granting great effects, but it opens the game up for more mind games, too.
Deploy may be the most disruptive mechanic of the three. It appears exclusively on Gear cards and allows you to play that Gear directly to a battlefield rather than equipping it to a unit. While deployed, the Gear provides its effect but becomes vulnerable — if your opponent holds that battlefield, the Gear is destroyed. Chai believes this will fundamentally shift how players approach defense:
"I think Deploy is probably the one that will disrupt [the meta], because historically, you don't think of just going straight to a battlefield. And now you have, like, Jarvan IV's E-Q, you have Ziggs just tossing bombs onto battlefields, and it's going to change the way people think about Defending quite a bit."
Chengran Chai, Executive Producer
Jarvan IV's "E-Q" that Chai references is the move combo in League of Legends where he throws his flag and then pulls himself there–pretty 1-to-1 with Jarvan IV's Legend ability in Riftbound, which lets you move a friendly unit to a Battlefield when you play a Gear with Deploy there (and pay 1 Power).
Radiance Pre-Rift and Sealed Hands-On
The Pre-Rift tournament provided a seeded deck alongside packs to build Sealed decks for testing. My Pre-Rift kit featured the orange Body and yellow Order Legend Jarvan IV, Exemplar of Demacia, whose ability synergizes directly with Deploy Gear. I supplemented the deck with Gear synergies, Bomb-generating Chaos cards, and Gold generation to fuel Jarvan's ability. The 7-cost Champion Unit Jarvan IV, Royal Heir got cut in favor of K'Sante, Courageous — a 5-rune Unit with Accelerate that proved far more valuable in the speedy Pre-Rift format where high-cost chosen champions often arrive too late to matter.
Initial skepticism about Jarvan vanished once the deck clicked. A key pull was the new battlefield Hunter's Circle, which reduces the cost of the first unit or gear each player plays there each turn by 1. This pairs exceptionally well with Deploy Gear since you choose when to play them. In my first test game going second, I played Concert Poster to Hunter's Circle for free, then returned it to hand to play Skystrike Squadron — a 4-Might Unit with Reflect — for a reduced cost of 3 on turn one. The following turn, Concert Poster created two Recruits while Pillaged Armory buffed both a Recruit and Skystrike Squadron. The sequencing felt powerful and repeatable.
Portable Portal deserves special mention. This 2-cost orange Body Gear with Deploy lets you pay 1 Body Power to ready a Unit when played, and friendly units at that battlefield gain Ganking. Combined with Jarvan's Legend ability, this enabled double conquering in a single turn or a Gank followed by a protective retreat. It's a rare card, so pulling it in Pre-Rift isn't guaranteed, but its impact is outsized.
Sealed Format Lessons: Bombs, Seraphine, and Chaos Staples
My two Sealed decks told different stories. One attempted a Seraphine build with Show Off payoffs and failed to cohere. The other pursued a Ziggs Bomb strategy using his Legend and the Epic-rarity red Fury Unit Ziggs, Short-Fused. The Bomb archetype proved tricky without reliable detonation on the opponent's turn — Bombs typically explode for 2 damage each when your opponent holds their battlefield, but forcing that scenario is difficult. Explosimian helps by playing three Bomb Gear tokens to a single battlefield, but this still leaves you vulnerable while holding that battlefield.
Before the Rift, the Ziggs dog‑eared deck sports a 4‑Might purple Chaos Champion Unit called Ziggs, Explosive. When it defends, it takes out a friendly Gear and, if that Gear was a Bomb, it gains an extra +2 Might. That makes the unit a straight‑up threat: fill one side of the board with Bombs and Ziggs, Explosive can destroy an entire attacking group before they even reach you. In the Sealed format, where that particular Unit isn’t guaranteed, players started making a split‑strategy. They’d stack Bombs on one side to keep the pressure high, then build a solid hold around strong Units on the opposite side,
Across every thrown-together deck, the purple Chaos cards Reckless Innovator and The Good Stuff proved universally useful. Their flexibility made them auto-includes regardless of archetype, suggesting Chaos remains the splash color of choice for Sealed consistency.
Key Takeaways
- Radiance is Riftbound's fifth set and introduces three new mechanics: Disarm, Show Off, and Deploy
- Deploy allows Gear to be played directly to battlefields, fundamentally changing defensive calculations
- Show Off creates information warfare by rewarding players who reveal cards from hand for bonus effects
- Pre-Rift and Sealed testing reveals Bomb strategies require specific detonation tools to function reliably
Radiance succeeds in its design goal: the base set provides enough depth for Sealed events to stand on their own, while the new mechanics add strategic dimensions that veteran players will spend months unpacking. Chai confirmed this was intentional:
"We want the base set to have a rich enough playing set such that Sealed events are fun all by itself."

The Bad Gamer Take
Riot Games will revamp the League of Legends TCG meta with Radiance because its new Disarm, Show Off, and Deploy mechanics punish static defenses and reward aggressive tempo swings. I predict that Akali and Vex players will ditch their classic Hold builds because Deploy forces them to rethink battlefield protection. Watch for how early adopters use Deploy
The collectibility layer — Alt Art, Overnumbered, and SP cards including Heartsteel and K/DA music crossovers — sits on top of a mechanically sound foundation. For competitive players, the meta shift toward Deploy and Disarm means Hold strategies need new answers. For casual players, the Pre-Rift and Sealed formats deliver the variety and discovery that make limited play compelling. Radiance launches with the complexity ceiling raised and the floor still accessible — exactly where a fifth set should land.
