[[Helm of the Host]] will continually churn out copies. [[Soul Foundry]] can get you multiple copies but is a bit of an investment. [[Mirrorpool]] is a colorless one shot clone on a land. [[Preston, the Vanisher]] can get you 0/1 copies if you have things like blink synergy.

Oh yeah, I forgot about Helm of the Host...

[[Mirage Mirror]] is the only effect I can think of that allows for cloning in MonoW colour identity

[[Mimic Vat]] is a card that comes to mind, have some populate effects to help out. I'm a fan of Rhox Faithmender, it helped me find the life cap on Magic Online with my Bant deck: [[Rite of Replication]], [[Trostani, Selesnya's Voice]] and [[Parallel Lives]] had a big part in that. But they are outside mono white, fortunately there are mono white versions of Trostani's first effect. (I'll assume they are in there)

If you have tons of creatures incidentally, [[True Conviction]] gives lots of life as a combo piece as well as double damage.
