Final wave: complete the 6th edition basic set (69/69 cards)
The hard six: AROUND THE CORNER attaches to any LOS attack and bends the sight line through one intermediate cell. BLIND victims lurch in die-rolled directions (bumping a wall costs the movement point, per the card) and their attacks fly wherever the die says — hitting whoever stands that way, or dissipating. UGLY drives every opponent in sight fleeing along shortest paths (breadth-first, die-broken ties) until they cannot see the caster. ILLUSION WALL is per-player reality: each opponent rolls 50/50 the first time it matters and the wall is real for believers forever — believers' views render it as a wall, the caster and those who saw through it get a ghostly dashed line, and Dispel Creation banishes it. ROTATE SECTOR turns a sector 90 degrees with every wall, door, wizard, treasure, object, firewall and alteration turning in place (the home star, being the exact center, never moves); RELOCATE SECTOR slides a sector anywhere that keeps all sectors adjacent, reassembling the map and recomputing wraparounds. Client: modifier attachment (Amplify/Add/Extend/Around The Corner), two-stage relocate, rotation direction toggle, dashed known-illusions. Every card in the 6th edition basic deck is now implemented. 81 tests passing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
