I have read this thread a lot when new posts show up. This is what I think.... JUST DEAL WITH RNG! Nutaku will not divulge numbers at any time. They may say "approximately", "above or below average", "I can't tell you" or some other statement to that effect. Unless you, yes YOU personally do your own tracking this thread is meaningless. I have tracked all the gifts I have given the rat and still know only this...

1 R-gatcha = best return on investment

Anything else = a waste of time.

The damn cards will drop when they drop.

Just because the drop chance is 10% (for example) does not mean a guaranteed drop in 100 tries. You could be that unfortunate asshole who spend 1000 tickets and only win once. Each spin is not conditional on the roll before or after it. ... trust me I miss 99.99% of the shit I want while I see others saying, "oh yeah every time I roll I win"..... Its RNG, just know that all 3 rarities of cards do drop from a single gift of an R-gatcha ticket. Eventually.
