 Strategy Article
There isn't a Horn of Plenty strategy article. Better players than I should improve this section, for I do not claim to understand Horn of Plenty play particularly well, and I know it's a tricky card.
Horn of Plenty can be one of the more difficult cards to use effectively. In a typical deck, it is not strong enough to be worth the opportunity cost of Silver, sort of like a finicky Workshop that can be played without an action.. Because it provides no coin, in the absence of sufficient variety to reliably gain cost cards or higher, it leaves you gaining low-cost cards that you may not want in your deck, and can be weaker than a
In order to get sufficient variety to make Horn of Plenty strong enough to be worth buying, it is usually necessary to have either cards giving +Actions, or alt treasure. A board full of terminal actions will favor Big Money or VP Rush strategies, neither of which synergize well with Horn of Plenty. Boards with a diversity of villages, especially those at different price points, work best.
Horn of Plenty works best with engines, but requires a certain type of engine, and sometimes requires slightly different strategies for constructing the engine. Single-card engines like Minion or Laboratory are less suited to Horn of Plenty than ones relying on multiple cards. Optimal Horn of Plenty strategies usually involve using Horn of Plenty both for engine construction and for gaining VP in the endgame. With many engines, it is easy to get 3-5 different cards in play - Village, Smithy, Copper, Silver, and Horn of Plenty is already 5 different cards, allowing you to gain even pricier engine components. In this manner, Horn of Plenty can be used like an Ironworks which takes more setup but can gain better cards. In the endgame, you can trash your Horns of Plenty either for Provinces (if you have enough unique cards to play) or for Duchies.
It is possible to build engines based around Horn of Plenty and a megaturn:
- Using Horn of Plenty, you build an engine that draws your whole deck
- You use Horn of Plenty to gain even more Horns of Plenty
- On your last turn, you play 8 different cards and cash in your Horns of Plenty for Provinces, ending the game.
Hunting Party synergizes well with Horn of Plenty, even though the two cards compete with each other as cost cards. Hunting party is a strong card on its own, but it is also guaranteed to draw a card that you do not have in your hand, thus increasing the value of each Horn of Plenty played after it. Hunting party is also a card that you benefit greatly from having multiple copies of, making it a good target to pick up with the Horn of Plenty once you get to 5 unique cards in play.
Horn of Plenty does not work well with Alt-VP, for the obvious reason that it is trashed if used to gain VP-Actions, and also because any pure VP that you draw gain cannot contribute to cards in play. However, some boards with Alt-VP can still have viable Horn of Plenty strategies: you can use coin to buy cards like Harem, Great Hall, or Nobles, which can provide variety to fuel using the Horn of Plenty's to pick up other cards or gain provinces. Although VP Rush strategies like Gardens or Silk Road do not work well with this card, Fairgrounds does, because both cards like variety, but also because Fairgrounds is a target for gaining in quantity in the endgame, rather than a card that you want to rush buying or gaining early on. Fairgrounds strategies are often more viable with Horn of Plenty on the board, because Horn of Plenty can be used to gain sufficient variety in the deck without using buy's.
- Games with Shelters give you a free Necropolis which can increase the value of Horn of Plenty.
- Horn of Plenty can gain cheap villages which can power a variety of terminals
- Menagerie, Fairgrounds, and Harvest also reward the variety that Horn of Plenty encourages.
- Combo: Horn of Plenty and Mandarin
- Black Market
- Hunting Party
- Big Money
- Alt-VP, including hybrid VP like Great Hall, Nobles, or Harem, but especially VP Rush strategies like Gardens or Silk Road
