Viktor Deck Guide 2026: Build Data + Standard Decklist
Subject of Legend Research #4 (2026-09-16): the series' lowest average score so far (7.6), but one of its most consistent builds. Best result: top 8 of the Summoner Skirmish 1-4 city event (6-1 in Swiss).
Direct answer
Viktor is the zero-divergence machine army: all 15 records run Viktor - Leader, and six cards — Sleeve Dagger, Cull the Weak, Loyal Artificer, Cosmic Singularity, Mother of Spirits plus Viktor himself — appear in every list. Trefilian Barracks is 15/15; the Mind:Order rune ratio floats between 5:7 and 7:5.

Build data: core cards
- Six cards at 100%: Sleeve Dagger, Cull the Weak, Loyal Artificer, Cosmic Singularity, Mother of Spirits, plus Viktor - Leader himself
- The first three average near-3 copies; Cosmic Singularity and Mother of Spirits average 2.5 — the tuning slots
- Thousand-Tailed Watcher, Royal Decree and Mech Preacher at 93% are nearly the 7th-9th core cards
Flex slots and findings
- The series' only zero-divergence champion: all 15 records run Leader; Innovator never appeared
- Runes are the divergence: the Mind:Order ratio floats between 5:7 and 7:5 instead of a flat 6:6
- At the 9/26 64-player city event, Viktor was the field's third force at 10 decks (15%)
Runes and battlefields
Battlefields: the series' second 100% — Trefilian Barracks in all 15; Wyrm's Nest 11, Grand Plaza 7. Runes are the flex: Mind:Order floats 5:7–7:5.
Sideboard
Scavenge leads (20 copies across 15 records), then Leona - Resolve and Skullcrusher. The 9/18 banlist barely touches Viktor: one record had Echo (Rewind) in the side; the standard list runs no banned cards.
Domain pair
Mind
MindTrap control. The most Hidden cards in the pool — set cards face-down and spring them at the worst moment for your opponent. With heavy Reaction and Vision-driven information, it plays a mind game of unseen threats.
Order
OrderGo-wide synergy. The largest pool (58 cards), with Action and Legion throughout, and Deathknell so losses still pay out. Wins on numbers and synergy — the army gets stronger together, and the opponent’s removal is never enough.
