Q can deal tons of % health damage, W is kinda meh but it works well with his passive, E is fucking useless if you ask me, R is Malzahar ult with spell vamp/gap close: good job you just played yourself. Nonetheless, I find it fun to play him since he gets underestimated so easily and you just end up 1v5ing the enemy team as a tank because they keep thinking 1 person is enough.
