Infinite mana

[Quackmaster5]

I know people have talked about the dead eye navigator and Zealous conscripts with guilder lotus trick.

Cheaper version is to replace  {Zealous Conscripts} with  {Flickerwisp}

It's not standard but definately much cheaper in terms of total mana cost.

So it's  {Flickerwisp} +  {Deadeye Navigator} +  {Gilded Lotus}

Flickerwisp won't quite work, it exiles its target until end of turn like {Venser the Sojourner}, not like {ghostly flicker}, making it impossible to loop any effects with it.
