New endless black mana

[Rasser]

{Drownyard Temple} SOL card
{Urborg, Tomb of Yawgmoth}
{Lake of the Dead}
{Retreat to Coralhelm}
  {Fatestitcher} /  {Kiora's Follower}


Just an easy 5 card combo. Lol

[Remillo]

Stitcher/Follower can also be replaced with Zendikons/Genjus or a Kormus Bell.

[Rasser]

Can also replace lake of the dead with anything that could produce 3 mana or more, and do some landfall shenanigans.
