Notes & Combos
Check out my latest replays to get an idea of how to use the deck even when going second.
2nd replay has a full combo OTK using Shooting Majestic with 2x attacks against full board Swordsoul.

I use it mostly to send any card I want to the graveyard (e.g. Stardust Trail since I'm adding Arrive in Light to my hand most of the time to summon the Shooting Majestic synchro instead of adding Stardust Illumination and I can only choose one of the two spells) so that's my main reason why I'm using Riser in my extra.
There are other reasons as well, for instance it can help me sending any light I'm missing resources for re-summon Chaos Ruler, and I like how it's a tuner that can be any level (7LV - 2LV) but these situations rarely come and not as useful in duels, but it's sending effect is the main reason why it's there.

hadn't thought about it that way, he is pretty easy to make and he does dump a card to the grave. Very Nice. Have you considered adding blazar or quasar?

Blazar and Quasar are both good boss monsters, but I feel like it's too much to add them in this build since I'm mainly summoning the Shooting Majestic, but I'll try the other builds later, and test if I can add both or remove the Majestic engine and bring only the Blazar. 👍
