Alternate pulls between Kazuha and Alhaitham until you get one, then save the rest.
Alternately, do that on a wish simulator and measure your reaction after you get one of them, then use that to determine which one you want.
Unless they do another archon stack like they did in 3.1, you should be able to save enough for all three.
