I found something terrible for you. Here you go.

Parallel Lives (x1)
Soul Foundry imprinted with Phyrexian Metamorph
Liquimetal Coating

I tap Liquimetal Coating, turning Parallel Lives into an artifact. I pay 3 and 1 blue mana for a Soul Foundry Phyrexian Metamorph Token. I get 2 (two) such tokens, due to my 1 Parallel Lives. All good so far. I make (2) copies of Parallel Lives. I now have 3 Parallel Lives, 2 of which are permanently artifacts. I can now do this (at least) once each turn.

Turn 1: 1 PL
Turn 2: 3 PL
Turn 3: 11 PL
Turn 4: 2059 PL
Turn 5: A number, which, if represented in decimal digits, is 620 digits long.
Turn 6: Oh, god, make it stop.

yeah, that gets a little nuts pretty fast. You can go much faster if you want (Xenograft naming Golem, Precursor Golem, Parallel Lives, Opalescence, and 2 kicked rites of replication back to back).
There you go.
