"As If": This was added to the FAQ (v.1.7, March 2020) and then amended (v.1.8, October 2020). You can read the October ruling on the ArkhamDB rules page here. (I'm adding a hyperlink rather than retyping the rules in case in future the ruling is changed or amended - at that point, the rules page will be updated and all ArkhamDB FAQ entries will link to the correct ruling.)

Q: Double, Double vs Pay Day. Can the of Double, Double be initiated despite the end of the turn [from Pay Day]? If the turn immediately ends, does this mean even if Pay Day is played again, no actions were performed and the second pay day will grant no resources? A: Technically, you can use Double, Double to play a card that ends your turn twice, even though it ends your turn. Ending your turn doesn’t mean that you can’t trigger effects, it just means that you can no longer take actions. Since the second playing of the card doesn’t cost an action in this case, you can go ahead and resolve it even though your turn has ended. HOWEVER, due to the specific text on Pay Day, doing so would essentially do nothing. It says that you gain 1 resource for each action you performed this turn. Since you are playing it outside of your turn, you would gain 0 resources from the second copy of Pay Day (since the first copy ended your turn.)

Q: Double, Double vs The Painted World. I imagine The Painted World cannot be played twice by Double, Double, since it's removed from the game, but can the copied event be played twice? A: You can absolutely use Double, Double to play The Painted World twice. Note that it says you play it “as if it were in your hand,” so each time you played it in this way, you could choose a different event beneath Sefina Rousseau. Keep in mind this may not work with some events (such as events that become attachments or go to a specific play area) as you only actually have one physical copy of The Painted World to move around. UPDATE: There is an extant ruling that one can trigger Double, Double after playing The Painted World (and target different cards no less). A recent ruling said that one cannot trigger double double after playing Cheat Death as Cheat Death will have been removed from the game as part of its resolution. As The Painted World is also removed from the game during its resolution (albeit with slightly different timing) is this ruling no longer valid? Would the same be true of any card removed from the game? A: Under current rulings, removing The Painted World from the game is a part of its resolution, so it would be an ineligible target for Double, Double. This does overrule the previous ruling.

Q: Can you use Double, Double on Scene of the Crime (as Tony)? Can you Double, Double with Evidence!? A: Yes, you can. You can use Double, Double on Scene of the Crime because it is still technically your first action (the second playing of the card does not cost an action). UPDATE: The Scene of the Crime ruling has been overruled by official FAQ 2.18: "If a card can only be played or its ability only triggered as your "first action," it must spend one of your actions, and that action must be the first one you have taken during your turn. If it is fast, a free triggered ability, ignores its action cost, or takes place outside of your turn, it cannot be played or triggered." ORIGINAL RULING CONTINUES: As for Evidence, it is a reaction to defeating an enemy, so as long as you are still in that same opportunity window (having just defeated the enemy), it is perfectly legal to use Double, Double to play it a second time. In this way, it’s no different from having two copies of Evidence in hand and playing both of them, one at a time.

Q: Regarding Double, Double, when is the time to trigger the ability in playing an event? When can I trigger Double, Double's triggered abilities, before or after the event card goes to the discard pile? For example:

• 1) When I played a Scrounge for Supplies and resolved the effect. Can I use the ability of Double, Double to resolve the effect of this card and return it from the discard pile to my hand? A: If you played Scrounge for Supplies, then activated Double, Double, you would retrieve Scrounge for Supplies from your discard and put it into Limbo (a liminal state, expanded upon in FAQ 2.0). It would not be in the discard pile at that time, and could not target itself.
• 2) When I played Delay the Inevitable and resolved the effect. Can I use the ability of Double, Double to play one again? If possible, is the timing of DD's triggering ability before or after this card's attachment to Investigator in play? A: Activating Double, Double on an event card that “attaches” would only cause that card to attach to something else, or reattach to the same element. This goes for Delay the Inevitable as well as cards like Reliable.
• 3) When I played Think on Your Feet and resolved the effect. Can I use the ability of Double, Double to play one again? If so, how do I resolve the effect? A: Playing Think on your Feet and activating Double, Double, would allow you to move an additional time before the enemy spawns, because a nested sequence off the same timing trigger has occurred.
• 4) When I played a Cheat Death and resolved the effect. Can I use the ability of Double, Double play one again? If so, what happens? A: Cheat Death must be removed from the game as part of its resolution. Double, Double cannot interact with it once it’s removed from the game.

Q: You explained that the trigger time points for Double, Double [see above] and Heirloom of Hyperborea are "after the Event/Spell card has resolved in full". How am I to correctly understand "This trigger occurs after the card has resolved in full."? According to your reply, I guess that a card is placed in play (e.g. attach to, in play area, in threat area), or in its owner's discard pile. Does this mean "this card has resolved in full"? What if a Spell Asset card is played, or an event card (e.g. Delay the Inevitable), in which case, at what point has "the card resolved in full"? A: For Heirloom of Hyperborea, it triggers after you play a Spell card. If the Spell card has a single effect like Ward of Protection and then gets discarded, you can trigger Heirloom once it’s in the discard pile. If you instead play a Spell like Scrying, you could activate Heirloom once Scrying enters play. A card like Delay the Inevitable, which stays in play after it is played, could become a target of Double, Double after it has been attached to an investigator.

Q: Double, Double reads "Play that event again as if it were in your hand." Does this actually mean "The same card is physically played twice", not "The second copy of the card was played by Double, Double"? If so, I play a Slip Away and fail the evasion test. Then, I trigger the Double, Double ability to "Play [Slip Away] again as if it were in my hand." If this skill test succeeded by 3 or more, can I return Slip Away (I mean the first card that failed the test, physically present, of course) to my hand at the end of my turn? A: Yes, Double, Double should be interpreted as physically playing the event card an additional time. Yes, you could fail the first test with Slip Away but succeed in the second to return Slip Away to your hand.

Q: Does the ability on Double, Double allow me to replay an event that removes itself from the game such as The Painted World? A: No. While Double, Double’s ability allows you to replay an event “as if it were in your hand”, it does not allow you to replay an event that has removed itself from the game as part of its effect. - FAQ, v.2.1, August 2023
