The obvious comparison is between this card and Emergency Cache, but the more pressing one is between Hot Streak and Another Day, Another Dollar. I think that Hot Streak has a place in a few decks, but you generally need to satisfy one or more of these conditions:
- Your deck will still have Emergency Cache. Emergency Cache is a good card, and 2 more copies of Emergency Cache + can be good for some decks (Leo)
- You're Sefina. Enough said, the card is absolutely insane with her.
- You're running 2 ADAD already and still need resources most games. I'm not sure what deck would do this, but it seems fun. Hot streak it up.
Otherwise, I'd strongly recommend just grabbing ADAD instead. The benefit of Hot Streak over an Emergency Cache is +2 resources; for just one more xp, you can get that benefit at the start of every single game (and not have to worry about hot streak's high initial cost).
Hot Streak (4) is more of the same, except even more variance-heavy. Unless you have ADADx2 or some insane draw power, grab ADAD first.
