And who knows... Maybe throw a Resurrección/Letzt Stil combination his way. Well, we've already seen his new Shikai, so...no duh.

As for beating Yhwach, no matter how powerful having the abilities of multiple races makes Ichigo, I cannot possibly justify his Shikai being more potent and destructive than the heat of the sun itself, not to mention Zanka no Tachi's other abilities (cut through anything forever, summon the dead, obliterate something in front of the wielder). I don't even think Yhwach's gonna be beaten through brute force like Ichigo's previous opponents, given his current position as the lynchpin of existence.

Also, I really doubt Ichigo possesses the capability for either Resurrección or Letzt Stil - the former because that's a technique exclusive to Arrancar due to how they seal their powers within their Zanpakutō, the latter because that requires a Sanrei Glove and Ichigo has barely anything Quincy on or about him right now.
