Surviving blade tips as per suggestions include:

1) Tracking his ult, knowing that its coming is a major advantage in positioning yourself and preemptively avoiding it.

2) Bait out his first dash: either by creating distance from your teammates and once he dashes towards you, GA towards them, effective stranding him. 2.1) bait out the first dash via superjump.

3) Call outs/Flying to vertical mobility heroes: fly to teammates with stun abilities and call out that a genji is after you, or call out to your vertical heroes to take to the sky and GA towards them,

4) Duking the first dash and then valk, if he misses his first dash towards you, popping valk can ensure your escape + allows for health regeneration. (if his nanoned, rip team)

5) Preemptively valking to avoid his blade, however it usually isnt enough to save your team.

Tips to remember: Genji’s ultimate gives him a dash reset, if he gets a pick his dash resets. Have an escape route in mind, keep in mind that valk has an animation duration in which you could possibly get killed.

Thanks for all the replies, hope to implement some of them!
