The supplier just means another moving part to me : how many clics you’ll use to find that and are those clicks worth vs the c. economy you make with it ? This is better than a gamble after install 4, no ?
Also, 1xinstall faceup / turn is even slower and predictable : corp won’t rez outermost and play hide & seek with CVS or Battys, or an occasional purge, that would make you trash GPIs.
The deck need more shade, and more early impact to me. And money. And cards.
Well, quite a lot in B&B. Invalid, to me. You need Acacia & Mamon on top of this imo, so you can reboot with ease the Turtle after a purge. Increasing Corp needs to purge AKA putting Tapwrm isn’t a great idea, so you play without it too (plus, if you plan is to keep the corp poor, don’t play Tapwrm).
You could have a look at Aghora / Xanadu.
Corp piloting against that is in the same family of general defense than Nasir, and this is slower than Reina…
