"Money is only a tool. It will take you wherever you wish, but it will not replace you as the driver." Ayn Rand depicted the reasons for including Emergency Cache with few words, but you surely expect a longer explanation.
An event that gives you 3 resources for one action sounds like an auto-include in most decks. It speeds up your initial setup: play Emergency Cache, play Leo De Luca or Dr. Milan Christopher and still have 2 actions and resources to spend. Mid-game it can fuel the "pump" skills, like Dig Deep, for you. Late-game it probably sticks on your hand as a "dead draw". Emergency Cache has no alternative use, no icons to commit to skill tests. With a huge resource pool, you can buy anything, but you need expensive cards in the sale, too!
As a rule of thumb, i would offer you Spiryt's advise: If you can see yourself spending more than one action per scenario fishing for resources, then this card is a great way of ensuring you have the means to play your most powerful cards.
With more packs being released, the number of economy sources will raise. Right now, the slot for Emergency Cache mainly competes with Burglary and Dr. Milan Christopher (with 0 xp) and Hot Streak(4). Especially the guardian class runs low on resources, in-faction there's solely Stand Together(3). In solo play, Lone Wolf always is the better alternative to Emergency Cache.
