Breach the Bastion Spire Deck Builder Classes Tier List (Nov 2026 Opinion)

This Classes Tier List ranks Breach the Bastion heroes/classes as a community meta opinion for November 2026. It is not an official Roblox or Cheesy Games Studios ladder. Sample size is modest: Brewer just launched, and matchmaking mixes skill levels. Use letters to start arguments, then prove them in runs. Parent hub: Tier List Hub. Relics: Relics Tier List.

Ranking criteria

• Early elite survival (including Frog Parasite pressure)
• Hallway speed without potion bankruptcy
• Boss closing power once engines online
• Co-op contribution (cover, AoE, regen, not just selfish damage)
• Pilot difficulty for average players

Snapshot tiers

Exact non-Brewer class names rotate with updates—grade roles if a rename lands. Brewer is named because the November 2026 patch made it a focal point.

S — Meta shapers (conditional)

• Brewer (co-op focus) — Spore Burst AoE + regen, Stand Guard cover, Alembic brew→block, and steam payoffs give the party a stabilizer who still clears packs. High ceiling when the pilot brews on purpose. See Brewer Class, Players Brewer, Brewer Update.
• Premier solo burst seat (whichever clear damage kit your lobby offers) — deletes elites before they scale; S when potions and thin decks cooperate.

A — Reliable climbers

• Brewer (solo) — Still strong with Alembic and spore lines, but loses ally-cover value; closer to A unless the pilot is excellent.
• Block-first traditionalists — Boring wins; excellent into early elites when removals arrive on time.
• Flexible hybrid seats — Adapt to relic spikes without bricking.

B — Playable, ask more from relics

• Setup-heavy engines that need Happy Flower / energy pieces before they shine.
• Pure greed damage kits that fold to Frog Parasite without potion discipline (Beat Elites).

C — Situational

• Novelty kits that steal shop priority without covering the party.
• High-variance event gamblers that punish four-player pathing (Co-op).

Brewer deep dive (why the grade)

Strengths

• Multi-enemy nodes melt under Spore Burst-style tools while regen softens mistakes.
• Stand Guard creates real co-op identity.
• Alembic links offense setup to defense—rare and valuable.
• Relics like Happy Flower and Ember Strike (cauldron region play) can turbo the plan (Relics Tier List).

Weaknesses

• Off-plan card soup tanks the grade overnight.
• Early elites punish you if you draft Steam Engine before block conversion.
• Sample size post-launch is still growing—expect letter drift after hotfixes (Updates).

Mode split cheat sheet

Seat	Solo	Co-op (4p)	Notes
Brewer	A–S	S	Cover + AoE regen
Burst finisher	S–A	A	Needs potion bank
Block traditional	A	A	Safe teaching seat
Greedy novelty	B–C	C	Hurts shared paths

How to use this list in drafts

1. Pick the seat you understand (Getting Started, How to Play).
2. Draft the archetype, not the letter (Deck Building).
3. In co-op, prefer one S stabilizer over four mediocre DPS clones.
4. Re-check after patches; letters lag reality.

Confidence note

We label this opinion with limited samples. If your personal win rate disagrees, trust your spreadsheet—and send better evidence after more climbs. Tier lists serve the Bastion; they do not replace it.

Pilot notes before you reroll

Spend three runs on a seat before declaring it C-tier. Misplays look like balance problems: skipping removals, emptying potions in hallways, or drafting Steam Engine before you can block Frog Parasite will tank any letter. Pair this sheet with Getting Started habits, then re-grade honestly. When Brewer feels weak, check whether you actually converted brew into block—or just collected spore namesakes.
