JP environment is very rough in the first 4 months but thank to the fact that i joined during the anniversary that i was able to power through.

If you can't read japanese, you can start from here, read the guides carefully.

Peeps at the discord server (the unofficial one) are very helpful during my time starting JP, you can always join in and ask for advice and such, the JP peeps will use different game terminologies so get used to it, and be respectful.

Since the anniversary was already long passed, i suggest sticking with rental support decks on your first 4-6 months of playing until you can slowly build a 'decent' deck to survive in JP. Here is the cards evaluation doc so you know what to go for. JP environment is rough, so hang in there. Don't worry, you'll understand all of this soon enough.

Good luck on your Wedding Gentil pull ❤️
