Teams featuring Isaak clear 88.4% of Meds Up attacks across equally weighted battlefields, with established attack and defense Meta bonuses.

Horde 6.5 / 10

Summons and decoys provide useful board control, but fragile positioning, Xybia synergy and refresh dependence limit reliable performance across teams.
