The build is actually really consistent. At worst case scenaro you draw more of the Spright side and go through a mini Spright combo line with the endboard being Gigantic Spright (1 material still), Djinn Buster, Spright Carrot or Red (or Smashers if you get it with Jet), and Sprind. At best your end board is the same but with Gigantic "Champion" Sargas and Therion "King" Regulus added which makes a really strong board. Also, almost always Regulus is the 5th summon so no Nibiru fear.
You add Regulus with Sargas and get Tallyho with the Branga search. Any question, feel free to ask and I'll answer.
