Which commander to use for as many combos as possible?

[blackychan1]

Commander {Johnny, combo player}?

[PrEZchoICE1]

{Rings of Brighthearth} + {Basalt Monolith} makes infinite colorless mana.

[rarehuntertay]

 {Nekusar, the Mindrazer} can have some damaging combos...

{Mind Over Matter} +  {Temple Bell}
{Enter the Infinite} +  {Hive Mind}
{Sanguine Bond} +  {Exquisite Blood}

Those are a few I have in my deck... And there's probably more I haven't discovered yet...
