This is a confusing card in my opinion. Does it save you the ammo cost shown after the action arrow? "You must still pay any additional costs on that ability, which can include spending additional actions." The text should refund you an action if it saves just the action. Instead everyone's in here confused about whether it saves you ammo beside the action arrow, or not.
This card is underrated by both newbies and veteran players alike.
For a 0xp card and 1 resource, your first failed test each turn gets converted into a draw action. Over the course of a typical scenario this will net you 6+ cards. More importantly, it means most failed tests are not wasted. They instead give you more ammunition for passing tests!
And there's also the Wayne Gretzky effect: you miss 100% of the shots that you don't take. With this item out, you don't have to go into every test with a high chance of success. If you're out accumulating clues just give it a try, maybe you'll succeed! You'll end up passing quite of a few of those tests and save yourself cards and actions. Conserve the skill commits for the second try. This is alluded to in the old review by Tsuruki23, and is borne out through experience.
Lastly, you don't need to have a massive portion of your deck devoted to a failure suite ("Look What I found!", Oops!, Dumb Luck, etc). Those are fine to pile on if you're playing Stella Clark and relying on a failure each turn. But their existence doesn't make this card any less worthwhile.
PS: if your deck concept has resources to spare (often when playing Bob Jenkins), consider pairing this with Track Shoes to generate a low-stakes test you can afford to fail most turns.
McJames' review covered my thoughts about this card pretty well. Just to add on to the list of other things Bide Your Time can help with:
-Waiting at a location for other investigators to apply their support cards
-Waiting at a location to support other investigators with commits / enemies
-Building up moves to avoid locations with end-of-turn effects
-If you're one of those weirdos (like me) who plays Suzi, you can wait one turn to build up your stats
Essentially, it's a one-use 0 XP Borrowed time. I think it's good deck filler and can help strip out inefficient turns, but can get sided out as you get more impressive cards that make the turns you do have more impactful.
Ok, I know that this is a bit stupid but, technically, you could play The Raven Quill, attach it to Astronomical Atlas... and later be able to commit que Quill to an skill test through the Atlas's ability ¿right? same with any card you attach to the Atlas by any means?
It is stupid because it is super-inefficient but, is it valid? additionally, there's no customizable ability in TRQ other than spectral binding applicable to the Atlas. Maybe supernatural record to fetch for another Atlas? If you use that one, you could fetch for a first Atlas and play it with TRQ attached to it, then commit TRQ to a test to have it back to your hand, then play it again to fetch for a second Atlas, commit it again (12 resources by now xDD) and play it to fetch for a second tome/spell you have writeen down in Endless Inkwell.
Just put 3 Astounding revelation to trigger for 6 resources during those fetchs... so the total cost would be 6+3+(third tome/spell cost).
Even better, what if you come across TRQ when using the Atlas's ability? it attaches to the Atlas and applies all its properties right away.. without playing it and paying its cost, costless and actionless
