This is not a voucher crate. It'd be cool if you did win a voucher, but it has barely any voucher returns. You are basically straight up paying for ingame stuff, especially elytras and other rare items. This also introduces the Sharp X sword and the Prot X armor set. Expect these to be more and more common in later crates as the season draws to a close.
It should also be noted that this crate isn't a great way to get Invaded rank or cosmetics. In fact, it has no "IRL value" beyond the Invaded ranks, which you really don't see much of in there. If you just want Invaded rank, buy it!
On average, you get 14.03% of your money in vouchers, plus 29.6m in in-game stuff and US$0.19 in IRL value (Invaded ranks) per purchased key. If you were to spend all the vouchers on more May keys, you would get 13.8m in in-game stuff and US$0.09 in IRL value per real dollar spent. (This defines the IRL rate).
