All-nighter sounds great on paper. Spend a to gain ? It's like the Runner version of Biotic Labor. However, when you think about it you're actually spending 2 to gain, well... 2. In a game where every click matters, spending a click to install on one turn seems inefficient. The other problem here is: what are you going to do with the 5 turn? If you're using that turn to Professional Contacts, or do anything non-combo related, you're doing something wrong. All-nighter can have some very powerful interactions: Wanton Destruction comes to mind first and foremost, letting you trash up to 4 cards from HQ instead of the normal 3. I can actually see All-nighter get used in a Comet Prepaid VoicePAD Hayley Kaplan: Universal Scholar deck, where you get even more value from your clicks. Now that Anarchs have Adjusted Chronotype, I could see Starlight Crusade Funding decks utilizing All-nighter to get more value from playing multiple double events in a turn. But hey, add this to the positives: it's 0 to install.
If you're playing All-nighter to just gain the clicks, you're using this card extremely inefficiently. If you make room in your decklist for this card, you want to be making the most from every click and as such this card belongs in more combo-heavy decks.
