I was looking through some old cards, and stumbled upon old man Wulff.

This might be an old question that has been already answered, but can I reroll twice in the same attack with Wulff if I exhaust him to take back a concentrate fire token after I've spent it during the attack?

Thanks in advance.

You can only resolve the same order once during the same round.

Spend token+token is not counted as a single resolution as token+dial does.

So no, you cannot.
