Even without the dressbloom mixup, I would describe this as one of the better deals Nutaku's run lately, so long as you're not too picky on which characters you randomly roll.
For basically the same price as Step 1 with the last Gacha, which got you just one 6* ticket, here you get a 6*, 12x 3-6 rolls, at least 2x extra guaranteed 5*s with a chance one is a 6*, and the gold / rainbow skillbloom / dressbloom combo.
The manyus are worthless but even without them, it's better than anything I've seen lately.
Now having talked up Nutaku up with rare praise for a change, please, RNG fates above, bless me with Tiger Lily and/or Hollyhock when I eventually attempt these rolls.
