On the 365th day Oasis gave to me.
100k Coins, 50 Coupons, 10 Seal Fragments and a Rename card for free.

Of course i'm not being serious but honestly, i don't mind how they do the whole 1 year celebration.

The current objective on their plate would probably rolling out the 3.0 next month or following which will add new Ninja, Clothing etc which imo would be something big enough to celebrate who knows
