Io's ultimate provides her invulnerability for a prolonged amount of time if you are trapped with a Terminus resurrecting using the ult to invuln through it, similar to Androxus' Reversal you can use your ult to wisk Term away before he can react.
When Strix goes into stealth, he's fairly loud, allowing you to be able to more accurately predict where they will be. Strix usually hides and peeks to shoot, but shoot once, teleport mid-long range, and he's toast after the second shot.
With good game sense & map awareness you can counter Androxus Ult. Use your ultimate directly on him (if possible) or walls near him. Hitting terrain will trigger AoE Stun and interrupt his ult. Good aim required.
Try to place an illusion off to the side of the battlefield to teleport back to if someone, especially someone like Ruckus, starts to target you. This will work even if the illusion expires, but try to keep one hidden from the enemy at all times.
Find where her illusions are and use that to your advantage. If someone targets her, she will likely try to teleport away and confuse you. Surprise her by having someone else near her spot or quickly running after her while staying away from enemies
