as said cleanse and silversash remove it.
Morgana's shield spell blocks it. Probably Sivir's shield spell too.
HP regen counters it. HP pots can help.
There are lots of ways.
Then try Malzahar. You don't get the ghost, which is a shame, but the high damage w/suppression is just insane.
or is it cleanse
you could try to make hiim use it early in a team fight by having the bruisers jump on him; else, just back off and try to use health pots or something
