Eternity Vessel and Aetherflux Resoivoir

I want to make the utmost jank deck with as many landfall create creature triggers as possible to protect myself until I can get [[Eternity Vessel]] and [[Aetherflux Reservoir]] on the board. My intention is then to play a mass landfall card like [[Splendid Reclamation]] or [[Famished Worldsire]] to get a lot of Eternity Vessel triggers.

Does this combo work:

A. I put 10 landfalls onto stack

B. Landfall trigger for Eternity Vessel, brings me up to 50 (let's say it has 50 charges)

C. I then use Aetherflux Reservoir to kill someone bringing me to 10 life

D. Landfall trigger for Eternity Vessel, brings me up to 50 (let's say it has 50 charges)

E. Rinse and repeat

Does this work?

My second question is using [[Alhammarret's Archive]] to double the life gain? Like if I was at 10 life and had 50 charges, I gain 40 life, so Archive makes it so I gain 80?
