Grand Arena Weekly

Click an archetype for its head-to-head row vs every other deck. Mirror matches are excluded from winrates and EV. Sparse matchups are shrunk toward 50% via a Beta(2, 2) prior; draws count as 0.5. Adj WR is the same matchup record converted from per-match ELO deltas (skill-controlled). Faded winrate / EV figures come from a small sample (under 10 matches) — single-event numbers are noisy, so read them as rough.
