Picking Androxus is a good idea to counter willo Her seedling with legend card can do 4250 if you use reversal you can do 4250x0.75=3187.5(more than her maximum health) It's difficult for she to hit you while flying

When Willo Ults, fly into the air as well to take her down. This makes it a lot harder for her to hit you, especially if you have good aerial movement.

If Androxus tries to flank and kill you, be careful where you shoot. If he uses Reversal, you can try to shoot behind him and use splash damage to kill him since reversal only takes damage from the front and Androxus can't shoot while in Reversal.

Never use seedling for androxus he can reversal up to 3187.5 If he is flying try to make him go near the wall so you can shot him easier Try to note facing him 1vs1

Androxus has telltale audio cues. Listen out for his Nether Step to know when he might be making a move against you.
