Choose a squad of different enemy types by weight, with no type twice

Drawing from a weighted list until you have enough different ones is slow and skews the odds when the list is short. There is a way to give every type one random score and keep the best few, so the likelier types are favoured exactly as the weights say.

Why this works

Give each candidate one score that is biased by its weight, then keep the best few. A heavier item tends to score higher, a lighter one can still win by luck, and no item can appear twice. One pass is enough, with no retries to skew the odds.

When not to use it

Skip it when repeats are fine or wanted, such as a squad that may contain several of the same grunt. Then a plain weighted pick each time is simpler. Also skip it for a handful of fixed combinations that you can simply list.
