Definitely a cornerstone card for Maria Hill that should be played as soon as you draw into it.

With her ability to move counters around, you are better off playing this card along with cheaper supports and charging the cheaper, weaker options for a couple of turns then playing the pricier support options in a turn where you'd have to use this card as a resource to do so. The pricier "helicarrier" options can always get pulled with your ability in AE mode on your following turns.

I'd argue this is the most important card in Maria's kit. I'll often run Superpower Training just to help make sure I can get this down on the board. It's mostly the fuel that keeps her Helicarrier engine running, but I'll sometimes throw an extra counter on Med Team to help keep Nick Fury topped up (which winds up being another 2 counters) or Support Staff for another wild. Plus you can use it to basically stock up on counters since Maria can move a counter from one support to another each turn. Just overall an invaluable upgrade.
