Strength of the comps you pick. Higher tier comps from our database lift this grade; off-meta boards drag it down.
EconB
How well you reach the level you should for your placement and avoid sitting on gold at the end.
ItemsS
How fully your boards are itemized and whether the items end up on carry units (4/5-cost or 3★).
ExecutionA
Did you place better or worse than your board's strength on paper? Finishing higher than your comp, econ, and items predict means you played the fights and positioning well.
FlexibilityC
Variety of comps you play and how uncontested your boards are. Locking one comp every game or forcing into contested units caps this; adapting to augments and openers raises it.
