The plascretes are just filling cards that can help you vs scorch, since you play tag-me. If you dont need them, you just use them to feed Apex using the ID ability.
Crescentus is just to derez Architect immortal bastard so you can apocalypse the s***t out of him. Infiltration is filling up deck slots, and can be really good to snipe installed agendas or check what Ice is on HQ before siphoning. If you don’t use it, you just eat it with Apex. The 2credits can help too.
(sorry if Im messing up with the quotes, first time using stimhack forum and Im a little dizzy)
EDIT: Now I’m trying with -1 Plascrete - 1 Infiltration +2 Uninstall (this event helps a lot with apocalypsing)
