Overview:

The Mimeoplasm Mutate deck focuses on stacking mutate triggers onto creatures while leveraging graveyard synergies. The primary strategy involves creating value engines through repeated mutate activations and using The Mimeoplasm as a late-game finisher by copying powerful creatures from any graveyard. Key mechanics include self-mill, mutate stacking, and +1/+1 counter synergies.

Primer:

Core Strategy:
This deck aims to create an overwhelming board presence through mutate stacking and graveyard recursion. Early game focuses on self-mill (Sultai Ascendancy, Forbidden Alchemy) and low-cost mutate targets like Mysterious Egg. Mid-game leverages mutate triggers for value (Auspicious Starrix for free permanents, Dirge Bat for removal). The Mimeoplasm serves as both a backup mutate host and a finisher by exiling high-power creatures from graveyards.

Key Lines:

1. Mutate Value Chain: Pollywog Symbiote reduces mutate costs while enabling card filtering. Stacking Auspicious Starrix mutations can cheat 4-6 permanents into play.
2. Graveyard Recycling: Boneyard Lurker and Otrimi, the Ever-Playful recover key mutate creatures.
3. Commander Finish: The Mimeoplasm copying Void Beckoner (deathtouch counters) or Titanoth Rex (trample) with +1/+1 counters from other creatures.

Mulligan Priorities:

• Require 1-2 early mutate targets (Mysterious Egg, Zagoth Mamba)
• Seek self-mill engines (Sultai Ascendancy, Titans' Nest)
• Keep at least 3 lands with color flexibility

Critical Interactions:

• Essence Symbiote turns every mutate into life gain and counters
• Brokkos, Apex of Forever provides recursive mutate fuel
• Mythos of Brokkos recovers key mutate creatures and fills graveyard

Weaknesses:

Critical:

• Graveyard hate (Rest in Peace, Leyline of the Void) dismantles both mutate recursion and The Mimeoplasm's ability
• Single-target removal on stacked mutate creatures (loses all invested mutations)

Moderate:

• Slow setup (needs 3-4 turns to establish engines)
• Limited protection for key creatures (only Unlikely Aid and Sudden Spinnerets)

Minor:

• Mana base reliance on tapped lands (7 enters-tapped lands)

Most Important Cards:

• Auspicious Starrix
• Pollywog Symbiote
• Essence Symbiote
• Brokkos, Apex of Forever
• Mythos of Brokkos
• Sultai Ascendancy
• Dirge Bat
• Boneyard Lurker
• Forbidden Alchemy
• Otrimi, the Ever-Playful

Attribute Ratings:

Speed: 4/10

• No fast mana or early combo potential. Requires T5+ to establish meaningful mutate stacks.

Resilience: 3/10

• Vulnerable to graveyard hate and removal. Limited recursion outside Otrimi and Boneyard Lurker.

Consistency: 5/10

• Moderate self-mill and card draw, but only 2 tutors (Mythos of Brokkos, Forbidden Alchemy).

Interaction: 4/10

• Situational removal (Dimir Charm, Golgari Charm) and no free counterspells.

Rating Justification:

This deck sits between "Focused Casual" (4.5) and "Optimized Casual" (5.0) on the rubric. While it has clear synergy and a focused mutate theme, it lacks:

• Fast mana/cheats to accelerate beyond T5-6
• Redundant protection for key pieces
• Game-ending infinite combos

It outperforms precons through synergistic value engines but folds to common interaction seen at higher power levels.

Power level: 4.5 - 5.0
