Sea Hag is an Action-Attack card from Seaside. It is a curser which puts Curse cards right on top of an opponent's deck; since it only costs , it is an extremely good opening buy, and can make an opponent draw a Curse as early as turn 4. Since it gives no benefit to the player who plays it and it gives out Curses, Sea Hag can make for a very slow game!
 Official FAQ
- A player with no cards left in his deck shuffles first in order to get a card to discard.
- If he still has no cards, he doesn't discard one.
- A player discarding his last card to this has the gained Curse become the only card in his deck.
- If there aren't enough Curses left to go around, deal them out in turn order, starting with the player to the left of the player who played Sea Hag.
 Other Rules clarifications
- Even when there are no Curses left, other players still discard the top card of their deck when Sea Hag is played.
 Strategy Article
Original article by theory
Sea Hag is a powerful card, and one you should almost always open with. As far as the Cursing attacks go, it doesn’t get any more direct than this. No need to wait for the reshuffle for Familiar and Witch to start having an impact; no, just drop a Curse on top of your opponent’s deck and guarantee that they’ll draw a dead card next turn.
Does this mean that Sea Hag is superior to Witch? Probably not—the fact that you spend an Action doing nothing is a huge drawback. So certainly Witch is the better choice if you open/ . But Sea Hag is strong enough that I would probably buy it with a / instead of waiting for Witch.
The exception is with certain counters that directly benefit from having a Curse on top instead of in the discard (Lookout, Upgrade, Masquerade, and Native Village chief among them); even a +1 Action/+1 Card Action and a trasher in hand means the Sea Hag Curse goes away pretty quickly. In those situations, you should probably delay getting the Sea Hag and hope to jump to Witches instead. (Note that in multiplayer games, multiple Sea Hags make Lookout a far less desirable counter, since it’s quite likely your Curse on top will get discarded for another Curse.) If Witches aren’t available, consider delaying your Sea Hag purchase until later in the game; delayed Cursing attacks can be quite helpful because your opponent will typically have diluted his trashing ability with other cards, and possibly even Remodeled his trashers away.
Note that this does not apply to generalized early trashing: there is no reason not to open Sea Hag/Chapel, since your Cursing significantly slows down his ability to trash. This is a general principle applicable to all Cursing attacks, but especially Sea Hag, since it’s available from the very first turn and is therefore guaranteed to hit your opponent before he is able to trim his deck.
After the Curses are gone, you should almost never play Sea Hag, not unless you know your opponent has a good card on her deck. Either she’s been buying Victory cards, in which case you don’t want to discard one of them, or she’s buying good cards, in which case discarding will let him cycle her new purchases in slightly faster. Try to get rid of the Sea Hag as fast as possible, even trashing it to the Chapel if you can.
On a side note: along with Militia, Sea Hag is one of those massively-benefits-first-player cards; if you’re lucky enough to hit another player’s Sea Hag in the early game, that’s basically GG.
Especially in games where the Curses cannot be trashed, Sea Hag synergizes with some alt-VP approaches, such as Duchy/Duke. In Sea Hag games, both player's decks are likely to fill up with curses quickly, and Sea Hag itself offers no benefit when played, so it will typically be a longer period of time before players are able to reach . In these games, Duchess also becomes stronger as it provides economy while being less likely to collide with desirable terminal actions.
- Trash-for-benefit cards (e.g., Remodel, Bishop, Salvager, Apprentice)
- Council Room/Vault, since they’ll be drawing a dead card
- Throne Room / King's Court (even though the benefit doesn’t strictly stack, all the Cursing attacks hurt much more when Throned or Kinged)
- Lookout, Upgrade, Junk Dealer, and especially Masquerade. Masquerade counters Sea Hag well enough that you might even want to skip the Sea Hag entirely; the other trashers merely mitigate the damage.
- Native Village
- The non-terminal +1 Action/+1 Card Actions, combined with trashing
- Reaction cards
- Other cursing attacks
- Your handsize-reducing attacks

 Secret History. Confusion left the main set due to not being different enough from Curse (and also because it required 30 more cards to handle it). So all of the Confusion-giving cards vanished or were changed. It may not even be correct to say that that card inspired this one. Anyway eventually I tried Curse-to-deck-top elsewhere, then moved it here as I wanted another attack and it fit the next turn theme. The discarding is just there so that multiple Sea Hags don't leave you with a stack of Curses on top of your deck.
