Overview:

This is a mono-green +1/+1 counters deck led by Bristly Bill, Spine Sower that focuses on leveraging landfall triggers to generate counters and build an increasingly threatening board state through counter multiplication effects.

Primer:

The deck's primary gameplan revolves around establishing early ramp through mana dorks and artifacts, then using landfall triggers from Bristly Bill, Spine Sower to distribute +1/+1 counters across creatures. The deck includes numerous ways to fetch lands and trigger landfall, while also featuring counter doublers like Branching Evolution and Hardened Scales to amplify counter generation.

The deck aims to snowball its advantage through cards like Evolution Sage, Forgotten Ancient, and Oran-Rief Hydra while protecting key creatures with cards like Lightning Greaves and Swiftfoot Boots. Card draw is tied to creatures with counters through effects like Armorcraft Judge and Garruk's Uprising, allowing the deck to maintain momentum as it builds its board presence.

Weaknesses:

• Highly vulnerable to board wipes and mass removal, with limited ways to rebuild quickly
• Relies heavily on creatures staying on the battlefield to maintain advantage
• Limited interaction with flying creatures
• Weak to graveyard hate and artifact/enchantment removal, though includes some protection
• Can struggle against combo decks due to limited interaction

Most Important Cards:

1. Hardened Scales
2. Branching Evolution
3. Evolution Sage
4. Sol Ring
5. Forgotten Ancient
6. Lightning Greaves
7. Rishkar, Peema Renegade
8. Garruk's Uprising

10. Armorcraft Judge

Attribute Ratings:

• Speed: 4/10
• Resilience: 5/10
• Consistency: 6/10
• Interaction: 3/10

Rating Justification:

This deck operates at a focused casual level, with a clear strategy but lacking the explosive power or protection needed for higher-power tables. While it can create impressive board states through counter synergies, it typically needs 8-10 turns to establish a winning position. The deck's reliance on creatures and limited interaction places it firmly in the 5.0-5.5 range, as it's more optimized than a precon but still vulnerable to disruption.

Final power level rating: 5.0 - 5.5

The deck features good synergies and a focused gameplan but lacks the fast mana and protection needed to compete at higher power levels. It's well-suited for casual tables where players can develop their board state over several turns without facing consistent combo threats or heavy interaction.
