There are a total 5 stages in Kuriboh evolution, including its most basic form. During each of these stages, you can choose to release your Kuriboh in order to obtain the corresponding Gift as per mentioned below. However, if you released your Kuriboh, you will not get another Kuriboh to evolve, throughout the duration of the event, so it might be wise to release your Kuriboh at the corresponding Gift you want to take, some tips here which you should know, are:
1. Ticket Rewards
The list of card rewards are the same for Sphere Kuriboh, Relinkuriboh, Kuribohrn, the difference is the foil quality of the card (Normal / Glossy / Prismatic), obviously Prismatic being the best choice. You are able to redeem this card according to your choice.
2. Rainbow Pack
The Rainbow pack at Kuribandit is a SR/UR card that is selected randomly from the list of SR/UR cards obtainable from Sphere Kuriboh, Relinkuriboh and Kuribohrn, therefore making this selection an inferior choice because you will not be able to choose the cards to redeem.
3. Duel Point
Although it is listed you can gain different amount of points depending on the type of duels you play (Ranked, Special, Casual, Duel World), the earning is only calculated on your very first duel after daily reset. So in order to gain 300 points, your first duel after reset must be either Ranked/Special Duels, or you can choose the x3 standard multiplier when dueling standard duelists, otherwise you will only gain 100 points and will not further gain extra points until next reset.

4. Kuriboh's Form and Rewards
You can only receive 1 Gift depending on which Kuriboh evolution you released, the Gifts are not accumulative.
As far as I know, no tickets lasts for more than a year, so even if Yubel is available in November 2019 you would still be unable to get it, since you got the ticket in September 2018, which means the ticket would disappear in September 2019, which is two months BEFORE November 2019.
Actually there was a bug where you could obtain all the awards on the 2nd kuriboh event without a single release. (This is the 3rd Kuriboh event). The 2nd was the retake for ppl who couldn't read the 1st time.

Honestly I don't get the fuss over prismatic cards. Unnecessary animation obscuring the otherwise potentially cool artwork...
the fuss is mostly because they are rare. plus prismatics give bonus points which make them really useful for farming, best farm prismatic is prob union attack, but i get your point too, the animation has no use otherwise.
