I'm thinking that as one of my engines, running a third Journey to Eternity will make my deck more consistent. Even if I have a Journey out transformed into a land, casting another Journey will help reanimate and cause ETB effects. It can also be good to have another copy in case the first one or two get countered, destroyed, or the creature gets exiled.
However, it's not always good to have multiple copies of Journey on hand, especially if I don't have creatures on the board. Then, should I be running another copy of a card other than Journey, given my deck list below? Or maybe my deck doesn't need another copy of anything else, so perhaps I run something crazy and "janky" like Impervious Greatwurm? I didn't run a 4th Carnage or a 2nd Chupacabra because of the high average CMC of 3.11, while running 24 lands - this number of lands actually works out well for me and I'm rarely mana screwed because of Llanowar Elves x4, Jadelight x3, Elvish Rejuvenator x2, Journey x2 (transformed), and Field of Ruin x2 (for color correction). So that's 13 cards that can help me mana ramp, or 37 mana cards with the lands.
