Overview:

This Simic deck leverages Gale, Waterdeep Prodigy and Master Chef to execute a synergistic +1/+1 counters and token strategy fueled by instant/sorcery recursion. The primary game plan revolves around casting multiple copies of Slime Against Humanity to create massive trampling Ooze tokens amplified by counter doublers like Doubling Season and Branching Evolution. Gale enables spell recursion from the graveyard, while Master Chef ensures all creatures (including tokens) enter with +1/+1 counters. Secondary threats include Fractal tokens from Deekah, Fractal Theorist and value engines like Tatyova, Benthic Druid. The deck wins through overwhelming combat damage with pumped tokens or finishers like Biomass Mutation/Return of the Wildspeaker.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Prioritize ramping with spells like Three Visits, Growth Spiral, or Harrow. Deploy counter enablers like Hardened Scales or Branching Evolution. Cast Gale early to enable graveyard recursion. Use cantrips (Consider, Brainstorm) to fill the graveyard and dig for key pieces.
2. Engine Activation (Turns 3-6): Start casting Slime Against Humanity to create progressively larger Oozes. Recast Slimes from the graveyard using Gale's ability when casting instants. Generate additional tokens/value with Deekah, Fractal Theorist, Adrix and Nev, Twincasters, Tatyova, Benthic Druid, or Ohran Frostfang. Protect key permanents with Heroic Intervention or Mutational Advantage.
3. Amplification & Win (Turns 5-8): Resolve counter doublers (Doubling Season, Branching Evolution) to exponentially grow tokens. Use proliferate effects (Experimental Augury) to add more counters. Deploy finishers: Cast Biomass Mutation for X=10+ to swing for lethal, use Return of the Wildspeaker for a massive pump/draw, or leverage Ohran Frostfang for deathtouch and card advantage. Recur high-impact spells like Genesis Wave or Rishkar's Expertise with Gale for explosive turns.

Mulligan Priorities:

• Keep hands with 2-3 lands (including UG sources), at least one ramp spell (e.g., Three Visits, Growth Spiral), and an early play (Gale, cantrip, or counter enabler).
• Prioritize hands containing Slime Against Humanity or a way to find it (cantrips).
• Hands with protection (Heroic Intervention) or a value engine (Tatyova, Benthic Druid, Ohran Frostfang) are stronger.
• Avoid hands lacking ramp, early plays, or Slime density.

Key Tips:

• Maximize Gale's Recursion: Sequence spells to maximize Gale's trigger. Cast an instant (e.g., Consider) to recur a sorcery (Slime) from your graveyard. Cast a sorcery (Slime) to recur an instant (e.g., Heroic Intervention) for protection.
• Protect Critical Mass: Use Mutational Advantage or Inspiring Call to protect your board when you have multiple +1/+1 counters. Decisive Denial fights threats or counters key noncreatures.
• Leverage Proliferate: Use Experimental Augury and Mutational Advantage to proliferate +1/+1 counters on tokens and land-based counters (Llanowar Reborn).
• Manage Graveyard: Ensure Slimes hit the graveyard for future recursion/scaling. Use Noxious Revival to rebuy key spells or disrupt opponents.
• Utility Lands: Waterlogged Grove and Cephalid Coliseum provide card draw/filtering. Ipnu Rivulet can mill yourself to fuel Slime or disrupt opponents.

Weaknesses:

Critical

• Graveyard Hate: Rest in Peace, Leyline of the Void, or Bojuka Bog cripple Slime scaling and Gale's recursion, removing the deck's primary engine.
• Board Wipes: Mass removal (Wrath of God, Blasphemous Act) devastates the token-based strategy. Recovery is slow without a draw engine in play.
• Anti-Token Effects: Torpor Orb shuts off token creation from Deekah, Fractal Theorist and Adrix and Nev, Twincasters. Cursed Totem disables Runadi, Behemoth Caller and Ohran Frostfang.

Moderate

• Counter Removal: The One Ring or targeted -1/-1 effects can shrink key tokens before combat. Lacks widespread counter protection.
• Stack Interaction: Minimal counterspells make resolving key doublers (Doubling Season) or finishers risky against blue decks.
• Land Destruction: Non-basic land hate (Blood Moon, Back to Basics) disrupts the mana base, slowing setup.

Minor

• Flying Threats: Struggles against evasive armies without reach/trample enablers beyond Slime's inherent trample.
• Artifact/Enchantment Focus: Heavy reliance on noncreature permanents makes it vulnerable to targeted removal (Krosan Grip hits doublers).

Most Important Cards:

• Slime Against Humanity (Primary win condition and engine)
• Doubling Season (Amplifies tokens and +1/+1 counters exponentially)
• Branching Evolution (Doubles +1/+1 counters, critical for scaling)
• Gale, Waterdeep Prodigy (Recursion engine enabling Slime recasts)
• Adrix and Nev, Twincasters (Doubles token output for massive boards)
• Deekah, Fractal Theorist (Secondary token generator fueled by instants/sorceries)
• Ohran Frostfang (Provides deathtouch, card draw, and combat leverage)
• Biomass Mutation (Primary combat finisher for lethal swings)
• Tatyova, Benthic Druid (Card draw and life gain engine)
• Heroic Intervention (Essential protection for board states)

Attribute Ratings:

Speed: 6/10

• Can threaten wins via overwhelming tokens around turns 7-8 with optimal ramp and Slime chains, but lacks fast mana or T1-4 combos. Doublers accelerate significantly if resolved early.

Resilience: 5/10

• Has protection spells and some recursion (Gale, Noxious Revival), but heavily reliant on the graveyard and vulnerable to wipes/hate. Recovery depends on drawing into engines.

Consistency: 7/10

• High density of Slimes (17 copies) ensures access, supported by cantrips and land-based draw. Tutors are limited, relying on raw draws and Gale's recursion for key pieces.

Interaction: 5/10

• Efficient targeted removal (Beast Within, Force of Vigor, Decisive Denial) and protection, but lacks counterspells and struggles against resolved noncreature threats. Proactive disruption is minimal.

Rating Justification:

This deck achieves Focused power through its high consistency and synergistic game plan, threatening T7-8 wins with Slime chains amplified by doublers. However, critical vulnerabilities to graveyard hate and board wipes, combined with modest interaction and speed, prevent higher optimization. Its performance aligns with the "Focused" tier (T7-8 wins).

Power level: 6.0 - 6.5
