you have an expected value of 5.96 after 4 rounds of 5 step up summons, so with exactly average luck you can get 5 event UR copies in 20 steps (assuming 50% pickup rate of either event UR vs other URs), meaning your median spend should be roughly 29.1k jewels. step 19 has EV 4.76, so just short on average. And then for 4 more pulls it becomes 100% guarenteed, which caps your cost at 36400.

Though as someone else mentioned, if you are aiming for 1 specific GUR out of 2 event units, there's a roughly 6% chance you won't get your desired GUR after 5 full laps (36400).

Better deal than box yes (median 39000, cap 42000).

This special summon has one of the best median costs ever for single target featured UR. better even than the old 5% special. normal step up has a worse median than flip dx, but this one has better median cost than flip dx, and better caps your risk to boot.

If you're a big spender this is not a bad deal (assuming you like and/or need the cards). for everyone else, it won't matter anyway.
