And now for the counters to the counters to karthus' ulti

Early game: Stay above ~200 health. Not up to you. If you get ganked you are not going to be able to influence with how many you leave. Most of the time you will make it out with enough health but if you happen to luck out of the gank with 50-100 health. Gratz you just died to Karthus' ulti. The same applies when setting up a gank of your own ofcourse. Or go ahead and towerhug with full health while getting your exp. denied for the entire early game.

Buying an elixer of fortitude. Sure you could do that, and it's smart to do that. But you still burned 250g. Letting the enemy team waste 250g is still a good ulti early game, and remember that they need to buy new ones after they pop it.

Buying magic resist. Would work if it wasn't for the fact that his ulti will still kill you when you luck out on a gank with only 50-100 health, wether you have that extra magic resist or not.

Mid-Late game: Spell block items (banshee, zhonya's etc.) Ok, this sounds viable and it could be viable, if it only wasn't so situational. Wether or not you have your items ready to counter Karthus isn't up to you, it depends on how the enemy team plays. If they trigger your banshee with an other spell or force you to zhonya due to getting focussed then you just lost your defense against Karthus.

BUY MOAR MAGIC RESIST !!!11 Ok, sounds logical (and it is). The problem here lies in the fact that against a Karthus with archaic knowledge and a void staff you just lost a lot of magic resist, combine this with the fact that his wall will burn 35 magic resist and you will find you need a lot of magic resist to counter this. Sure you could stack more and more magic resist, but tanking purely magic damage leaves you vulnerable to physical damage whilst keeping in mind that at least 3 guys on your team should be focused on stacking other things then magic resist. (e.g. stacking attack damage)

Imo, every counter to this ulti is way too drastic in terms of cost, build order, lane control/exp gain. Sure you need to be mindful of the enemy team's abilities and you should adapt your tactic to the enemy team's playstyle. But wasting 90/150g on a ward or buying that bit of extra armor early on doesn't compare to what you need to counter this beast of an ulti.
