Nope unfortunately i couldn't test it cause i haven't got enough Gacha Seeds for the Gacha Trick and it's a pain in the ... to get new Gacha Seeds because Event Farming...
Today i pulled without the Gacha Trick and well... i can see the difference... With the Gacha Trick i have got at least one 5* with every 10+1 Pull^^
I have 5000 Nutaku Gold left. Maybe i will try a 10+1 next Wednesday at 15:50 UTC+01:00 (Berlin). We are living in the same time zone so it's easy for use to share data
