Puppet portalcraft, 2 points followers Rosa or Icarus

I've recently completed the puppet deck that can be found on this site (https://shadowverse.gamepress.gg/deck/11411/dbne-puppet-portal-rotation-format-masters-rank) and I wonder why he is using Icarus, since it will be hard to draw the artifacts in time for them to be useful since i need points late game for orchis and noah. I'm thinking of using Rosa instead to help me survive mid-game ,what do you think? Since i dont have Rosa yet, I'm using mechanized servants in the meantime for a resonance rush.
