A per-card rating of every Defect card in the STS2 v0.102.0 build, grouped by the four archetypes the character supports: Orb decks, Status decks, Power (Creative AI) decks, and 0-Cost (Claw) decks. Includes exact damage, block, and Orb numbers.
Defect returns in STS2 as a hidden character you unlock through the Epochs system. Mega Crit kept the core — four Orb channels (Lightning, Frost, Dark, Plasma) plus a new Glass Orb — but the supporting cards shifted sharply.
Permanent Focus stacking was nerfed: there are fewer ways to stack Focus outside a single turn, which hurts the classic Focus-tower build. In exchange, Claw decks (Scrape, All for One, Feral) and Status decks (Gunk Up, Smokestack, Trash to Treasure) gained enough support to stand as independent archetypes.
This article rates every Defect card by which archetype it serves. Cards that only work in one archetype are flagged; cards that work in all decks (like Coolheaded and Boot Sequence) are called out as auto-picks.

Defect Card Analysis — Every Card Rated by Archetype build priorities
This page covers every known Defect Card Analysis — Every Card Rated by Archetype archetype in the current Early Access build, ranked by consistency and scaling ceiling.
Each build section names the core cards, key combos, and the relics that push the archetype from functional to dominant.
Start with the S-tier build if you want the safest path through Ascension.
Open the related cards and relic pages if a build depends on a specific card or relic interaction.
Treat these rankings as an early-access snapshot — balance patches will shift them.
Defect starts with Strike, Defend, Dualcast, and Zap. Dualcast evokes your rightmost Orb twice and drops to 0 cost on upgrade — it is the defining starter and the reason every deck can burst with stacked Lightning or Dark Orbs.
A handful of cards are good regardless of archetype. Grab them in Act 1 even before you've committed to a build direction.
Defect's common attacks split between Orb enablers (cards that channel an Orb), Claw scalers, and raw damage. Know which role each card fills before drafting.
Cold Snap (1E, 6 damage + channel Frost) and Ball Lightning (1E, 7 damage + channel Lightning) are the most efficient common channels — they attack while building your Orb engine. Barrage deals 5 damage per channeled Orb and scales into a high-teens nuke once you have 3+ Orb slots.
The uncommon attack slot is where archetypes differentiate. Scrape and All for One power 0-cost decks; Null, Shadow Shield, and Consuming Shadow power Dark Orb decks; Synthesis is the keystone of Creative AI Power decks.
Scrape (1E, 7 damage + draw 4, discard any drawn card that costs more than 0) is the defining 0-cost card. Upgraded draws 5. With Feral out, every 0-cost attack returns to hand, so Scrape essentially finds 4 free plays per cast.
Defect's skill and Power layer is where you pick archetype commitment. Skip the wrong Power and you brick your draft; take the right one and the deck runs itself.
Creative AI (3E, start of turn add a random Power to hand) is the namesake card of the "Creative AI" archetype — it costs 2 upgraded and snowballs fast because every Power you draw feeds Subroutine.
Rare Defect cards are mostly archetype-specific bombs. Seven Stars isn't here (that's Regent) but Hyperbeam, Meteor Strike, Helix Drill, and Ice Lance fill the same role.
Hyperbeam (2E, 26 AoE, −3 Focus) is the cleanest 2-cost AoE in the game but the Focus cost kneecaps Orb decks that can't replace the 3 Focus. Upgrade bumps it to 34 AoE. Take it in Status decks (no Focus needed); think twice in Orb decks.
Defect has four viable archetypes in v0.102.0 and each has its own must-have cards. If a draft doesn't offer two of the must-haves by Act 1 boss, pivot.
The Orb deck is the most consistent because Defragment + Hotfix + Modded + Capacitor form a stable engine. The Claw/0-cost deck has the highest ceiling but needs All for One and Feral to function. Creative AI is boss-killing but slow. Status decks are balanced and punish Act 2 Status-applying enemies.

FAQ
Defect is balanced but not top-tier. The author of the Gamersky guide phrases it as 'greatly buffed compared to STS1, but the monsters scaled faster.' Orb decks still struggle against high-damage elites in Act 2 because Focus no longer stacks permanently, so your defensive Orb output is capped. Use Genetic Algorithm and Boot Sequence to bridge Act 1, then commit to one of the four archetypes.
Biased Cognition and Defragment used to stack Focus without a ceiling in STS1. In STS2, Biased Cognition drains 1 Focus per turn, and most cards now use 'gain Focus this turn' wording. The result is that you can't tower Focus to 20+ by Act 3 boss — your baseline is 2-4 Focus. That's why Capacitor (Orb slots) and Defragment (permanent +1/+2 Focus) became the real scaling anchors.
Claw itself (0E, 3 damage scaling +2 per Claw), Beam Cell (Vulnerable), Go for the Eyes (Weak on attacking enemies), and Adaptive Strike (creates a 0-cost copy in discard). Pair with Feral so each 0-cost attack returns to hand after play, then use All for One to pull all 0-cost cards back from discard for a second wave. Hotfix gives +2 Focus this turn to boost the final Claws.
Yes if you've got replacement Focus, no if you haven't. Hyperbeam's −3 Focus hit is crippling for Orb decks because your Frost Orbs immediately stop generating block. In Status decks with Flak Cannon and Iteration, you don't need Focus at all, so Hyperbeam is pure 26-34 AoE value. In Orb decks, take Meteor Strike or Shatter instead.
Creative AI (3E Power, 2E upgraded) adds a random Defect Power card to your hand at turn start. Combined with Subroutine (Power → +1 Energy), every Power you draw is net-free, which lets you stack Storm, Thunder, Echo Form, and Bulk Up in the same combat. The archetype is slow because Creative AI costs 3 Energy to set up, so you need to survive 2-3 turns before it snowballs. Pair with Boot Sequence and Genetic Algorithm to absorb early damage.
Upgrade it. Upgraded Zap costs 0 and channels 1 Lightning. It becomes a free Orb generator that triggers Storm, Subroutine, and Thunder. Same for Dualcast: upgraded Dualcast costs 0, which means you can evoke the rightmost Orb twice per turn for free once your Orb engine is online.
