Achieving a \"Simple geometry" during the Hanzo (Overwatch)

All the gifts. Play over a very long time and can not beat achivku for Hanzo called Simple Geometry. Particularly difficult this also this game was when it was neverknwo about a year ago. Previously, you had to just Recoleta hook 3-target and kill them. And now this spell has 6 quick shots and that's the problem...
The aim remains the same, you need to kill three targets, but with crooked hands like me, it is very difficult, as you need to do three targeted assassination in one application of the new flurry.

Any thoughts/ideas how to easily accomplish this achivku? I have tried many times to play partnered with the Rhine, which if successful ultimate had offered to land 3-4 opponents, but I don't have time to kill them. Same thing tried with may, several freezes when she does not have time to whotnot 3 goals. Did all the achievements except Doom Fist, Zen-atty and Hanzo (in the last stuck specifically).
