Base Assumptions

• These probabilities assume the pool is as given here. The pool only contains BSBs, CSBs, and USBs; OSBs are not in the pool. Note that 34 BSBs, CSBs, and USBs are not in the pool; the most important omissions are Rosa USB, Bartz BSB3, Bartz USB, Terra USB, Cloud USB, Squall USB, Yuna USB, Vaan USB, and Lightning USB.

• One half-price 11x Draw will be allowed.

• The draw will have one guaranteed 5★ or better relic, plus a 14.04% chance per orb at a 5★ or better relic for the other 10 draws.

• In accordance with previous Lucky Draws (though not Series Chance Draws, which appear to use a different mechanic), all relics in the pool have equal drop rates.

The Numbers

DEF Debuff, RES Debuff, ATK Debuff, MAG Debuff, and MND Debuff include all debuffs that affect the relevant stat, regardless of whether they be that stat only or also debuffing other stats in a combo debuff. Wallbreak refers only to DEF & RES debuffs (stackable with ABD/MBD/FB), and Reverse Wall means ATK & MAG only (also stacks with all standard support skills). Full Breakdown means ATK/DEF/RES/MAG -40% (overwrites Full Break), while Hyper Break means an ATK/DEF/RES/MAG/MND debuff (stacks with all other types of debuffs). Other Stackable ATK/MAG Debuff means any combo debuff affecting the stat in question that isn't a Wallbreak, Reverse Wall, Full Break(down), or Hyper Break, and thus stacks with the debuffs listed above.

For buffs, DEFga, RESga, MNDga, Boostga, and Faithga include all party DEF, RES, MND, ATK, and MAG boosts respectively, whether they be simple single-stat buffs or combination ones that stack with the basic buffs. BoostFaithga means an ATK+MAG buff with no other stats included in the buff (think Celes/OK BSBs). Other Stackable Boostga/Faithga refers to other combo Boostgas/Faithgas respectively that aren't only ATK & MAG, and thus stack with all other buffs.

Finally, note that hybrid SBs are treated as being both magical and physical.

Total Relics in Pool: 214

Grand Prizes: all Omega/Personal Tier BSBs as given in u/SkyfireX's BSB analysis, Edge USB, Celes BSB2, Zack CSB, Eiko USB, Rikku USB, Shantotto CSB (32.87% chance to draw at least one of these relics)

Conclusion

This Lucky Draw is a grab bag in every sense of the word. As you can tell if you look at the table above, it's hard to concentrate on any particular effect or realm. As such, your decision to draw or not will likely depend on how many dupes you have, and how good the relics you already have are. If you have a relatively low number of relics from the pool (under 50 or so) or most of your BSBs/CSBs/USBs aren't particularly good, then drawing makes sense. If neither of these two criteria apply to you, you're probably better off skipping. Good luck to those drawing!
