Legacy Infect one year performance analysis

Here's the full Legacy Infect breakdown over the past year (July 2025 – July 2026):

🧪 Legacy Infect — 1-Year Performance Analysis

Legacy Infect exists across three tracked variants. Here's how they stack up:

📊 Winrates (excl. mirrors, last 12 months)

Archetype	W	L	D	Winrate	Matches
Bant Infect (WUG)	29	40	0	42.0%	69
Simic Infect (UG)	45	77	2	36.9%	124
Sultai Infect (UBG)	2	5	0	28.6%	7

All three variants underperform the 50% baseline. Simic Infect is the most-played but the worst performer. Bant Infect is the strongest performing variant, though still below parity.

📍 Meta Presence

Infect (combined) holds a fringe position in Legacy. For context, the top archetypes (Dimir Tempo, Izzet Delver, Show and Tell) each command 6–8% meta share. Infect variants all sit well below 1% individually — this is a rogue/specialist choice, not a staple.

📈 Simic Infect Trends (most-played variant)

Presence has been sparse and inconsistent throughout the year — usually 1–3 entries/week when it shows up at all, with large gaps in representation. Best stretch was late Nov / early Dec 2025, where it posted ~37–44% winrate across 31 matches. A brief bright spot hit in late April 2026 at 57% WR (small sample: 7 matches).

Bant Infect had a strong run in Feb–Mar 2026 (75% WR one week, 50% another) but sample sizes are small.

🃏 Core Card Package (Shared by Both Variants)

4-ofs in virtually every list:

Noble Hierarch, Glistener Elf, Blighted Agent, Inkmoth Nexus
Force of Will, Daze, Brainstorm — blue tempo shell
Invigorate, Berserk — pump suite
Legolas's Quick Reflexes (100% presence) — the new Lord of the Rings protection spell
Embiggen (95–100%) — heavy pump adoption

Bant distinction: Adds Savannah (and likely white sideboard/tech options like Swords to Plowshares targets or white hate pieces).

🏆 Context vs. the Meta

The Legacy meta is currently dominated by Dimir Tempo (52.2% WR), Dimir Reanimator (53.3%), and Doomsday (53.3%). Infect's glass-cannon game plan struggles in a meta heavily featuring FoW mirrors, Daze wars, and resilient blue control/combo decks.

Summary: Legacy Infect is a fringe, high-variance archetype that clocks in at ~37–42% winrate depending on variant. Bant slightly edges Simic on performance. The deck is not competitive in the current Legacy landscape against the tier-1 blue decks.
