Summoner Spells

For Amumu I only use the top two Summoner skills but there are others that are viable.
Teleport: This spell can very useful and which is why it is recommended as the second spell. It can be used to go to a minion or turret, which can help in ganking or advancing turrets/defending turrets.

Flash: This spell, is chosen because it is better than Ghost, but can be used to 'flash' in quick or out of any situation.

Ghost: This spell is a backup if your not level 12 to use Flash.

Teleport: Good for farming and protecting from back-doors & ganking.
Flash: Good for running, recommended for level 12+.
Ghost: Good for chasing, recommend for under level 12.
