which mages can kill a tank
even with void staff they still have a lot of hp

Kite them ->

can take down tanks pretty well since they have low cooldown abilities or a constant source of medium-high damage.
Cassiopeia, Swain, basically every dps mage because dps counters durability.
Downside is that it's not one and done like burst mages. You gotta commit.

Azir comes to mind if played well.
All of them, given time.
Generally the idea is DPS>Durability>Burst>DPS so tanks inherently counter champions who are cooldown reliant like many mages and assassins but are killable by carries and some mages
Cassiopeia and azir come to mind as mages who can kill tanks, brand too but he has a huge %health dmg source in his passive and frequently builds liandry's ehich burns health
First of all, why are you even targeting a tank? Second of all, all DPS mages can if they're fed enough.
comes to mind.
Azir if you can kite well
