it's better to focus chronos at first to get up your healing output, but when you have it at least at lvl 2, focus deft hands to help with your stuns. never go for reload speed with your cards. use your cards in a better way by focusing healing.
Create a loadout that has snake pit II or III in it (probably less if you have two tanks to heal) and practice nailing your stuns. If you stay grouped and land a stun, evie will get deleted. Try to stun her right as she comes out of ice block.
It's tempting to get deft hands when you know you'll have difficulty with flanks, but you should get your reload speed from your loadout instead. This will allow you to get cauterize so you can keep down the enemy frontline and help your tank further
This is not entirely true; with the right team comp and skill level he can actually counter Evie and juke her with slither. Be careful of his wekono’s curse talent and snake toss when combined you’ll be at his mercy.
Just be careful with dealing with him. Like most recommend advice try an land a shot from midrange and blink up close to him. Most likely though he’ll slither away and hug his tank or predict where you’ll land then stun you. You need to ULT him.
