"I would hate if that was true, he has a letter of his own, let him use some original powers, and preferably one that wont require a major asspull for ichigo to win at the end"

I must have been reading a different series, because the battle against Aizen was nothing but asspulls to defeat an all-powerful opponent. I have no reason to suspect otherwise with Yhwach.

Also, what makes you think Yhwach's Schrift isn't "The Absorb" or "The Amalgam", and his power isn't to have everyone's powers combined because King of the Quincies?
