Pros:

- Great minion farm
- Heavy damage on single target
- Good game in early, mid AND late game
- GREAT style of dancing

Cons:

- Needs a lot of mana
- Very squishy
- First target in every team fight

For Summoner Spells, there are different possibilities:

1. Spell: I would always take "Flash", because it often saves your life

2. Spell: In my oppinion, there are several options:

- Clarity (to spam your abilities in early game)
- Ghost (Another "surviving tool)
- Ignite/Exhaust for killing champions

For killing one champion, Malzahar has a spell combination for a safe kill:

1. Attack the enemy champion, so he is on half health
(Be sure that the enemy doesn't have Flash)
(Use an offensive Flash)
2. Cast "Call of the Void"
3. Use "Malefic Visions"
4. Cast "Null Zone"
5. Use your Ultimate "Nether Grasp"

= Save Kill

Malzahars Ultimate is very powerful. You should always ensure, that the target is arranged in your spell "Null zone".

The Ultimate can mean your death to, because you can't move. Be sure, that you are surrounded by your team, when you use this Spell.

Farming is very important for Malzahar and one of his advantages over other champions.
During the early game, you should max Malefic Visions, because it's Malzahars most powerfull spell to farm minions or to harass enemy champions. This spell jumps to another minion (or champion), if the first enemy dies. So you should always focus enemies (minions) with low health.
