What is Trap in Legends of Runeterra?

Legends of Runeterra has many card effects that are common enough that they get their own keyword - a word or two that immediately tells you how the card works. Let's take a look at the Trap keyword.

Attaches to another card, trapping it. When the trapped card is drawn, perform the effect.

Trap is a very obscure keyword, only appearing on one card in the entire game (kinda contradicting the usual introduction there), and a token at that, Poison Puffcap. The card is generated by Teemo, Puffcap Peddler, and Mushroom Cloud. Mushroom Cloud itself is also generated by Clump of Whumps and Chump Whump.

Keywords that Work Great with Trap

Although there are no keywords that directly synergize with Trap itself as a mechanic, there are keywords that synergize with the gameplan of having your opponent draw all the Puffcaps. Challenger and Lifesteal will allow you to stay alive as your opponent draws more Puffcaps. Any future Trap cards will also share the same non-direct synergies for the same gameplan.

Playing Against Trap in Legends of Runeterra

Playing against Poison Puffcaps is fairly easy for most decks. Aggro will often rush through anyway before many are drawn, and Control may have the ability to heal and negate the Nexus damage. Teemo leveled up can create problems if left unchecked, so save some removal or Challenger units for it if possible.
