Most UAE batsmen got out to simple deliveries. Pakistanis aren't that inept.
From what I have seen of Varun today, he seems to be an inferior version of Mujeeb and Ghazanfar. Even RizBabar spanked around Varun in 21WC ! Maybe he has improved by I will back Farhan to smack him out of attack during PP.
Axar Patel is Nawaz level bowler. If you can hit a few boundaries early against him, he will go into defense mode and will be easier to deal with.
Kuldeep is the real threat. He bowls slow which is ideal for Dubai with near 80m boundaries. Hopefully, Fakhar can line him up for a few sixes. Fakhar has dominated leg spinners like Shamsi and Sodhi before. He has hit sixes against Kuldeep as well but gave away his wicket at times. Should be a good contest between these two.
If we can counter Kuldeep, rest won't be much of an issue.
