Overview:

This Riku of Two Reflections deck focuses on spell/creature copying synergies and infinite combos, leveraging the commander's ability to duplicate value-generating creatures and game-ending spells. It combines ramp, card advantage, and combo potential with moderate interaction.

Primer:

Core Strategy:
Deploy Riku by turn 4-5 using 12+ ramp sources, then chain copied spells/creatures to generate overwhelming value or infinite combos. Key phases:

1. Setup (T1-4): Ramp with Sakura-Tribe Elder, Cultivate, and land-fetch creatures. Dig for engine pieces with Fact or Fiction/Expressive Iteration.
2. Engine Activation (T5+): Cast Riku with protection mana up. Copy mana dorks (Coiling Oracle) or combo enablers (Peregrine Drake).
3. Win Conversion: Use infinite mana from Peregrine Drake + Deadeye Navigator to fuel Capsize locks or Ral, Storm Conduit damage. Backup plans include Dualcaster Mage + Twinflame token armies or Rite of Replication on value engines.

Mulligan Priorities:

• 3+ lands with at least two colors
• 1-2 ramp spells (prioritize 2CMC like Nature's Lore)
• At least one card draw/selection spell
  Reject hands without early green mana or that rely solely on 4CMC+ plays.

Key Tips

• Sequence copy effects after Riku triggers resolve for maximum value
• Use Solve the Equation to tutor combo pieces like Reiterate
• Hold Narset's Reversal for protecting critical turns
• Mystic Sanctuary enables graveyard recursion of key interaction

Weaknesses:

Critical

• Dies to graveyard hate (Rest in Peace disables recursion engines)
• No free counterspells to protect combos

Moderate

• Slow recovery from board wipes
• Limited stax interaction beyond Reclamation Sage

Minor

• Some tapped lands slow early development
• Relies on commander for maximum efficiency

Most Important Cards:

• Deadeye Navigator
• Peregrine Drake
• Dualcaster Mage
• Twinning Staff
• Rite of Replication
• Solve the Equation
• Reiterate
• Ral, Storm Conduit
• Archmage Emeritus
• Storm-Kiln Artist

Attribute Ratings:

Speed: 6/10
Can assemble T5-6 infinite mana/damage combos with optimal draws but lacks fast mana acceleration.

Resilience: 5/10
Moderate recursion (Eternal Witness, Regrowth) but folds to multiple commander removals or graveyard hate.

Consistency: 7/10
12+ ramp sources, 8 tutors/card selection spells, and redundant copy effects enable regular combo access.

Interaction: 6/10
Decile counterspells/removal (Counterspell, Beast Within) but lacks free interaction and relies on sorcery-speed answers.

Rating Justification:

The deck's ability to consistently threaten T6-7 wins through multiple combo lines places it in optimized casual tiers, though reliance on commander and absence of cEDH-level fast mana/protection cap its ceiling.

Power level: 5.5 - 6.5
