Real versions of this comp's final board: which exact group of champions shows up together, how often, and the average placement of those games. Not a game-by-game history (Riot only exposes the end-of-game board, never how it got there): a comparison of builds, not a timeline.

Board add-ons (9th/10th unit)

Base board — 8 units 3.06 avg placement · 36 games

+1 unit (9 total)

Alistar 2.00 avg placement · 2 games

The main board above stops at 9 units: reaching a 10th slot needs level 10, which on its own already correlates strongly with a good placement. Below, the average placement of games with this base board plus one or two extra units, shown as a correlation to interpret, not a causal recommendation.

Incomplete attempts grouped here

Caustic Master Yi 7 units 35 games · 5.69 avg placement

These comps share a strict subset of the units above (never an extra one) — likely attempts at this same comp, stopped partway rather than distinct archetypes.

Augment path

Data unavailable. Riot's API doesn't populate the augments field for this set — verified directly on the collected sample (the "augments" field doesn't even appear in the response, across 23,000+ real participants checked). The field does exist in the official schema and worked on older sets, so this probably isn't permanent — this section will activate automatically as soon as it fills in again.
