Learn how to add promo Building cards like The Pigsty to your Card Wars deck, from checking rules to shuffling and storing them safely.

Quick answer

To use a promo Building card in Adventure Time Card Wars, treat it like any other Building: confirm it’s legal for your play group, add it to your deck’s Building section, and follow its printed rules. For The Pigsty, that means giving your Pig cards a boost when it’s in play.

Promo Buildings are still Buildings

Promo cards like The Pigsty Promo Building Card are not a separate card type. They follow the same deck-building and play rules as Buildings from the core set. That means you count them toward your Building limit, shuffle them in with your other Buildings, and play them during your Build phase just like any other Building.

The main difference is availability: promos often come from Kickstarters, conventions, or promotions, so your playgroup may not recognize them. A quick rules check before the game avoids mid-match disputes.

The Pigsty’s specific boost

The Pigsty is a fan-chosen promo from the Adventure Time Card Wars 2025 Kickstarter. Its printed ability gives your Pig cards a serious boost, turning them into what the card calls “full-on power porkers.” That means the card is most useful in a deck that already runs a solid number of Pig creatures. If you have only one or two Pigs, The Pigsty will rarely justify its slot.

Because the exact boost text is printed on the card, read it carefully before you build around it. The card does not list a deck limit beyond the normal Building rules, so apply the standard limit from your core set.

When to leave the promo out

Promo Buildings are not automatically better than core Buildings. The Pigsty is a niche card: it rewards a Pig-heavy strategy but does little for a mixed or Creature-light deck. If your deck wins through spells or non-Pig Creatures, a generic Building from the core set may serve you better. Also skip it in formats that restrict promos or in sealed/draft play where your card pool is limited to what you open.

Steps to add a promo Building to your deck

Check promo legality with your group: Before you shuffle The Pigsty into a deck, ask your opponent or playgroup whether promos are allowed in the format you’re playing. Some casual groups allow all promos; others restrict them to specific events. If you’re playing in a tournament, check the organizer’s promo policy first.
Count it against your Building limit: Promo Buildings count toward the same Building limit as core-set Buildings. For example, if your deck allows 8 Buildings, The Pigsty takes one of those slots. Don’t add it on top of a full Building set. Remove one existing Building for each promo Building you add.
Read the printed ability and plan your deck around it: The Pigsty boosts your Pig cards, so include enough Pig Creatures to make the boost relevant. A common mistake is adding The Pigsty to a deck with fewer than four Pigs, where its effect rarely triggers. Count your Pig cards before you commit; aim for a meaningful number, not just one or two.
Shuffle it in with your other Buildings: Treat the promo like any other Building during setup: shuffle it into your Building deck. Don’t keep it separate or set it aside, or you’ll change the odds of drawing it. If you’re using sleeves, sleeve the promo in the same color as your Buildings so it doesn’t stand out.
Play it during your Build phase: On your turn, play The Pigsty from your hand during the Build phase, following the normal timing for Buildings. Its ability applies as soon as it’s in play, so sequence it before you play Pig Creatures if the boost is immediate. Announce the boost clearly so your opponent knows which Pigs are affected.
Store it safely between games: Promo cards can be hard to replace, so keep The Pigsty in a sleeve and store it with your deck rather than loose in a box. Avoid leaving it in direct sunlight or a hot car, which can warp cards. Use a rigid deck box and consider a second sleeve for extra protection.
