Onifundo say "At THE BEGINNING of your main phase you can pay the cost" [Soulblast 1 and return this unit to your hand], so you make the skill and you may call this card to rear circle but you cant make the efect to second time because when you call a card to rear circle is not THE BEGINNING main phase
I disagree with that. He can use that skill cuz beginning of main phase did not end it's end when u got nothing to chain. Maybe, u will understand by playing CFV in 3DS
hougen skill choose only grade 1 and grade 2, you cant choose grade 0 to copy it. kinda misplay on the yasuie player and the zangeki user I think he didnt discard for buster skill.
