if you open with snake rain and no scareclaws and one level 4 ogdoadic use snake rain send nunu nauya keruse and aleirtt summon nunu from graveyard keruse effect tributing nunu then keruse effect to summon nauya then nauya effect add water lily or serpent strike. normal your level 4 ogdoadic xyz for rikka then tribute it for aleirtt. add back nunu and nauya to the gy and summon hypertyon. then keruse and aleritt for number 38. only do this if you have no scareclaws as they need to be normal summoned to start their combo most of the time.
for scareclaws any combo will work a great endboard is to have tri heart number 26 as well as astra acro and any other scareclaw on the field. at the start of the battle phase activate number 26 effect targeting tri heart and attack directly 3 times for well over lethal. for number 26 when you use it on your battle phase make sure you have lethal otherwise your going to give you opponent a 3000 atk monster and on your opponents battle phase either use it on their strongest/best monster to have it for your next turn or their weakest or one that cant attack.
a great endboard is triheart number 26 astra acro king queen scareclaw straddle and scareclaw sclash (you can swap out the king/queen for other scareclaw monster or monsters from your extra deck)
