Deck-Building FAQ

Q: How many cards does my deck contain in total?
A: 53 (50 cards + 3 LEVEL1 waifur)

Q: Can i add more than 3 LEVEL1 waifur cards to my deck-folder?
A: Yes, there is however no way to use those additional LEVEL1 waifur during play other than "charging".

Q: Can i use 3x the same LEVEL1 waifur?
A: Yes, although this is generally not recommended.

Q: Can i add LEVEL2 and LEVEL3 waifur cards to my deck that are not of the same name as my LEVEL1 starters?
A: Yes. (See rules for <CROSS-UPGRADE> within "COMMON-ACTIONS" section of this page)

Q: Why does the single CHARACTER-PACK i bought not contain enough cards to build a deck?
A: PROJECT:WAIFUR is sold via CHARACTER-PACKs, which contain every single card connected to the promoted character as full playsets. These packs allow you to chose and pick your favorite waifur and customize your deck-folder as you please, without any restrictions or additional costs that would come from a standard TCG BOOSTER-PACK-system. Instead, PROJECT:WAIFUR requires you to buy 3 CHARACTER-PACKs to play, allowing you to expand your card-library with each additional set.

Q: Can i combine more than 3 CHARACTER-PACKs?
A: Yes, you can combine any card of any set in a deck-folder as long as you remain within the playset-restrictions.

Q: Are there any prebuilt decks availiable?
A: There are no purchaseable "trial-decks" or "starter-decks" by design. There are also no plans on releasing any in the future.


\ Every waifur has her own zone on the field.
\ Card-effects will only apply to the waifur they are installed to and her programs, unless there is specific wording.
\ Both players may at any time look at the cards within their own
COOLDNOWN-ZONE, CHARGE-ZONE and CACHE-ZONE, but not of the other player.
\ Every time the DECK-FOLDER is searched, it must be shuffled afterwards.



Playmat FAQ

A: Any cards sent to COOLDOWN by normal means are always sent to COOLDOWN3, while COOLDOWN4 can only be accessed via card-effects.

Q: When does the CACHE-ZONE come into play?
A: The CACHE-ZONEs (3 seperate zones located underneath each waifur) can only be accesses through card-effects.
Cards are usually placed into CACHE via the <CACHE> common-action (See common-actions section).
Outside of card-effects, the only way to interact with cards within CACHE is when a waifur is deleted, as all cards attached to that waifur, including CACHE, are sent to COOLDOWN.

Q: How exactly do i position installed cards on the board?
A: Be crative! It is advised to place installed cards somewhere below or near the waifur they are installed to.
The only rule is to make it clear and obvious which card is attached to which waifur.

Q: What is the maximum limit of cards in HAND?
A: Unlimited.


The player to go first must skip COOLDOWN-PASE,
DRAW-PHASE and UPDATE-PHASE in their first turn.

Keywords FAQ

Q: How exactly does UNIQUE work as a condition?
A: Any card-effect with a condition including the keyword UNIQUE can only be used once a turn, but not only by that card but in total by any card of the same name. The moment a card-effect with UNIQUE activates, no other card of the same name can use that card-effect during that same turn. This only counts per player, the same rules apply for your opponent, but seperate from you.

Q: Can FACE-DOWN cards activate card-effects?
A: No, any FACE-DOWN card is treated as if it has no card-effects.

Q: Can card-effects activate from HAND or if not installed?
A: Yes, \\\global card-effects will always activate while FACE-UP (no matter the ZONE) or also from HAND if the wording specifies it so.

A: Yes, but only \\\global card-effects can activate outside of being fully installed. (via <INSTALL>, which is part of the <DOWNLOAD> common-action)

if they do, \\auto and \manual effects can not activate.

Q: Can i <CANCEL> any <INSTALL>?
A: No, you can only <CANCEL> the <DOWNLOAD> common-action.
If a program would <INSTALL> through other means (like card-effects), you can not use <CANCEL>.


The main battle in PROJECT:WAIFUR happens during the ACTION-PHASE!

The turn-player may do any of the following in any order:
\ <DOWNLOAD> programs from HAND
\ Activate card-effects
\ Use <CANCEL> during their opponents <DOWNLOAD>

The opposing player may do the following:
\ <DOWNLOAD> programs with {REVERSAL} from HAND
\ Activate quick card-effects
(with specific conditions like "during your opponents turn")
\ Use <CANCEL> during their opponents <DOWNLOAD>

When your waifur is deleted:
Remove and send SCORE to your hand equal to the waifurs LEVEL+1;
<DELETE> all attached cards including CHARGE, CACHE, upgrades and programs;
then place the LEVEL1 waifur back to FACE-DOWN position on the field.

You win the game if any of these conditions are met:
\\ Your opponent must remove or take from SCORE but can not.
\\ Your opponent must <DRAW> but their DECK-FOLDER is empty.
\\ Your opponent has no active waifur.
\\ A card-effect states that you win the game.

It is highly recommended during early turns (until turn ~5) to always <CHARGE> all of your waifur! You generally want to get the additional DRAWs during DRAW-PHASE (1 for each waifur that can <DISCHARGE>x1) to get your economy and COOLDOWN-rotation going. A game between advanced players will mostly get to turn 5 within 10 minutes and would be finished by turn 10.

Combat FAQ

Q: How do i count damage?
A: You can keep track of CDMG and PDMG by either writing it down, or more commonly by using dice, placing them next to or on top of the cards.
Many values for HP and PP have been created with the use of dice in mind.

Q: What happens if a FACE-DOWN card is deleted?
A: That card is sent to COOLDOWN as by the regular rules for <DELETE>.
If a card was deleted FACE-DOWN, it had no card-effects, therefore even \\\global card-effects will not activate.

Q: What does "specific wording" for targeting mean?
A: Specific wording includes:
"Another ally":
"Another ally program":
"Another program":
Any of your cards
Other than the activating waifur
Other than the activating program
Other program from the same waifur
Your opponents cards

Q: Can i <CANCEL> my opponents card if they <DOWNLOAD> during my turn?
A: Yes.

Q: How do i read card-effects and conditions correctly?
A: First, determine what type of effect it is: \manual, \\auto, or \\\global by looking for \ \\ \\\ at th beginning of a card-effect.
Then ( ... ): if availiable determines the effect-conditions.
If the conditions are met or there are no conditions at all; follow the instructions of the effect-text.
For \manual card-effects, you can choose when to activate them, either during <INSTALL> or during your turn.
\\auto, or \\\global card-effects have to be activated when the conditions are met, unless the effect-text itself states otherwise (for example by adding a "may" to the wording).
All wording on PROJECT:WAIFUR cards is generally very direct and straight to the point.
