Overview:

A mono-green +1/+1 counter deck led by Bristly Bill, Spine Sower that combines landfall triggers with counter manipulation to create an exponentially growing board presence.

Primer:

This deck operates on multiple synergistic axes, primarily focusing on landfall triggers to generate +1/+1 counters through the commander while utilizing various counter doublers and enhancers to amplify the effect. The strategy involves aggressive land ramp through numerous fetch lands and land tutors, which trigger Bristly Bill, Spine Sower's ability to continuously grow creatures. The deck includes several ways to play additional lands per turn through cards like Azusa, Lost but Seeking and Oracle of Mul Daya.

The secondary strategy involves powerful mana generation through cards like Nyxbloom Ancient and Selvala, Heart of the Wilds, which can fuel the commander's counter-doubling ability. The deck can win through combat damage with massive creatures or generate infinite mana combinations with cards like Staff of Domination and large creatures. Card draw engines tied to both creatures and counters ensure consistent access to resources.

Weaknesses:

The deck is vulnerable to board wipes and mass removal, particularly those that exile since many protection pieces only grant indestructible. Heavy counter removal or prevention effects can significantly hamper the deck's primary strategy. The deck can struggle against heavy control strategies that prevent creatures from staying on the battlefield, as the commander's ability requires creatures to target.

Attribute Ratings:

• Speed: 7/10
• Resilience: 8/10
• Consistency: 8/10
• Interaction: 6/10

Rating Justification:

This deck demonstrates significant optimization with a robust mana base, efficient ramp package, and powerful synergies that can create overwhelming board states by turn 5-6. While it lacks the explosive speed of higher-powered decks, it makes up for it with consistent growth and multiple layers of protection. The deck sits above typical focused decks (6.0) due to its efficient execution and resilience, but below highly optimized decks (7.5) as it doesn't consistently threaten wins before turn 5. The inclusion of premium interaction and protection spells, along with multiple paths to victory, places it firmly in the focused competitive range.

Final power level rating: 7.0 - 7.3
