Feed Mythic Deal your 99 and the manual re-writes itself around the cards you actually sleeved: opening keeps, goldfish turns, kill routes and the politics that fit your curve.

Keep/mull heuristics written against your real land count and ramp package.
Turn-by-turn curve maths so you know which round your deck comes online.
Every line in your 99 that actually closes a four-player pod, ranked.
When to look scary, when to look broke, and who to point the board at.
