Safe From All Sides
Nested squares rotating in alternating directions. Four gaps — one per side, at each midpoint. No front, no back. Every direction equally defended. Used by Bhishma (Day 9) and Shalya (Day 18 — the final day of the war).
The Reversal — all squares simultaneously flip direction. If you are mid-gap, you will be crushed.
