How does Vel'Koz counter health-stacking? If anything, health-stacking is a counter to him.
Velkozs passive deals %health true damage upon activation
No it doesn't.
Oh mb your right I forgot it deals true damage but not % health, Vel'koz generally builds first or second item
as it activates fully on every ability of his besides his W. As such Vel'koz deals considerable amounts of % HP damage and general true damage making him quite effective with dealing with tanks.
Eh, liandrys isnt a great second buy. You get the guise, then finish it for a 4th item, i believe.
Synergy with Liandry's Torment (every move except W applies CC), low cooldowns (so he as decent sustained damage), and he can kite many of the health-stacking champions.
Like EndlessSorcerer posted the synergy with liandry's is very powerful. However it is also the passive while it may not be % damage it is damage that is not mitigated by resists giving you consistent damage over time. His low cooldowns combined with CDR also is a major contributor to team damage.
I mistakenly thought his passive was %HP too, mb....
is a pretty good choice then, as his passive adds %max health damage to all his abilities and
is pretty core on him which adds %current health damage.
is also good because of his W (and again add Liandry's)

If by AP you mean Burst AP, then there's little you can do. Burst really isn't meant to take out tanky targets. You might get away with AP DPS with Cass, or Malz, and using Liandry's.
Otherwise, the health stacker shouldn't be your primary target. As AP Burst, You either want to burst down the enemies Squishies, or attack multiple Targets with AoE. But you main target shouldn't be the Juggernaut.
does extremely well against heavy health tanks.
is good for mages.
is good as well, but for champs who build more armor.
Anyone who does % health damage or just build
,
, 
Play a champion that uses BOTRK or does health % damage.
k thx

Buy Liandry's, Void Staff, and Abyssal scepter if they're stacking MR. Rylai's is also good for the slow and it will extend the duration and amp the damage of Liandry's.
Vayne, Fiora, Blade of the Ruined King, Liandry, Brand, Malzahar.
If you're ad, Botrk, and the last whisper upgrade. if you're ap....good luck to you sir
start playing as ap varus he does % hp damage and can burst anyone down in like 2 secs
I would say...a combo between high CDR, Rylias and Liandries Torment, you can't burst them but you can tear them to shreds over time and stay out of range in most cases, downside, you lose your "I DELETE YOU" vs their adc, but if you are having that much trouble with their front line you'll never do that anyway.
