I like the looks of math's second idea. However, upon examining it in greater detail I'm worried by the lack of some of the cards I would consider Life's "staples". I expect there will be several cases in the middle of War where we redesign a certain remaining deck to meet what we have left in our Vault. This consequently means that we will need to run on a backup supply of certain cards that were not previously placed in the deck, but are now needed for what we hope to do.
In other words, I think that what would be best for the remaining cards is to focus on what else from Life we need to take to cover the basics. Cards such as Mitosis, Frogs, Dragons, Heal and Adrenaline. Also, disregarding the fact that we don't have Mitosis included yet, if we want to open up the possibility of using MitoDragons then we may want to consider adding 2 Chimera.
As much as I'd like to include a second Frogtal or PUgon, I'd also like a reserve to fall back on in the event that we lose critical pieces to any of our decks due to a loss, penalties, event cards, etc. But my opinion is always subject to change. If you have a proposition that you feel would work for us using the remaining 46 cards according to math's breakdown #2, everyone here is all ears.
