Optional: you can use shiny phantom foxy(JUST FOXY, NO PATRIOT SHIT AND ALL) and get it something like withered or pnm. Optional: you can also use shiny hawaii endo(lower value than shiny endo) Optional: You can also bring mangle(cheapest secret according to me)
How I got phantom Freddy was completely odd I went into endless three I was just waiting for the enemies to come out yet they didn’t come out and I got to wave 120 (max wave) then boom phantom freddy
he's worth around 600-700 souls this is a website that shows the value of units in souls: sites.google.com/view/fnaftdvaluelist/units/secrets?authuser=0 some people will make you overpay
if u mean starters like $300-1000 to place down that u can still get now, then i recommend phantom foxy and phantom cupcake theres not that much starter units that are actually good that you can still get good starter units include endo-2, patriot freddy, pirate foxy, and a few others but those you will have to trade for if u want to get one of those starter units that i just listed, recommend farming phantom presents and then selling them for souls to people, then with the souls u earn, you trade them for one of those starters sites.google.com/view/fnaftdvaluelist/units/banner-endless-units?authuser=0 -- this website shows the prices of each unit in souls
The tip is good n all but tbh phantom freddy isn't rlly that good and pretty mid. Its value is also insanely bad. But i aint complaining as it could be useful for others.
