Caitlyn Teemo Deck Guide

All-in mushroom archetype has not been considered meta for a while now - but the fun of it has always been there.

Hello there! In this article, I’ll be featuring Teemo Caitlyn Poison Puffcaps deck.

The archetype isn’t a popular meta pick up but it is one of the most enjoyable decks to play on ladder for me. The mushrooms win condition can be high variance – either stealing wins for you or leaving you devastated.

Teemo Caitlyn’s objective is to plant Poison Puffcaps and Flashbomb Traps in your opponent’s deck. Poison Puffcaps act as your primary win condition that deals damage to your opponent’s Nexus whereas Flashbomb Traps are more of a removal tool for low health units.

Cards like Teemo, Puffcap Peddler, Lecturing Yordle, and Ava Achiever are your main tools to plant Poison Puffcaps into your opponent’s deck.

While you’re working on your Mushroom-planting, your opponent will look to end the game as soon as possible. Stinky Whump acts as an early chump blocker that also helps with Poison Pufffcaps.

Caitlyn is a solid 3-drop champion that provides Flashbomb Traps which will come in handy to control the board. Leveling up Caitlyn in this deck isn’t a difficult task either, after which she will become the main threat for your opponent and will force an answer out of them.

Once you’re done with your Puffcaps planting it’s time to accelerate things a bit.

The deck runs two methods to get those Puffcaps triggered. First, Corina, Mastermind allows you to activate all traps in the top 5 cards in your opponent’s deck, can be a winning play if you’ve planted a lot of Puffcaps.

Second – forced card draw. The deck runs a lot of cards that make your opponent draw, like Veteran Investigator, Aloof Travelers, and Insider Knowledge, which will all trigger the Poison Puffcaps.

Techs and Options

  • Puffcap Pup: A good early unit that can plant Poison Puffcaps onto the opponent’s deck, the Quick Attack allows the unit to go in aggressively in the early game. You can cut Stinky Whump for Puffcap Pup if you favor planting more Puffcaps early on.
  • Get Excited!: A more burn approach to close out the game, can also come in useful to remove certain units off the board. It’ll be diffcult though to find a card to discard from your hand. Can be ran in the deck instead of Poison Darts.
  • Thermogenic Beam: a removal tool that can come in handy to keep control of the board, the spell also triggers your Puffcap Peddler‘s ability as well. You can cut Poison Darts for it, but usually, you don’t want to run more than two as it can be a brick.

General Tips

  • Keep your Puffcap engine safe. Puffcap Peddler is your opponent’s worst nightmare.
    They’ll be looking to remove it as soon as possible. Outside of Stress Defence, your deck doesn’t run any protection tools, so don’t risk losing Puffcap Peddler in combat. Avoid blocking with him unless it’s necessary.
  • Make sure to plant Poison Puffcaps before going for card draw.
    The more Puffcaps you plant in the deck the more likely your opponent will draw more per card, forced draw is the way to accelerate the damage your opponent takes, use it wisely.
  • Leverage Caitlyn’s pressure. Leveling up Caitlyn in this deck is quite common.
    Her damage potential can be increased if you play Corina, Mastermind, or force your opponent to draw cards, hence activating the traps in the deck.
  • Ava Achiever is a game-winning card. If you have an Ava Achiever on the board it will double all the traps activated. Combined with Corina, Mastermind, and card draw, Ava Achiever can close out the game pretty fast.


Mulligan for: Teemo, Caitlyn, Puffcap Peddler, Lecturing Yordle.

  • Your opponent’s main win condition is through The Bandle Tree, you’re going to have to close out the game before they play 10 units of different regions.
  • Try to remove Bandle City Mayor off the board as soon as possible to prevent your opponent from swarming the board, Mystic Shot can take care of the job.
  • Do not block with Puffcap Peddler as it’ll make it vulnerable to Ravenous Flock or Pokey Stick.
  • It’s fine going low on health in this matchup, outside of Pokey Stick your opponent does not run cards that can burn you down.
  • Preventing Bandle Commando from hitting your Nexus and creating a Hungry Owlcat is important as it makes it harder for your opponent to play a unit from the Ionia region.

Mulligan for: Teemo, Caitlyn, Puffcap Peddler, Lecturing Yordle.

  • Teemo is great early game, it serves two purposes, plant Poison Puffcaps into your opponent’s deck and blocks Zoe from attacking.
  • Zoe striking your Nexus means they could potentially create an Equinox off Supercool Starchart. Equinox can shut shutdown your Puffcap Peddler.
  • Play Aloof Travelers before your opponent has the chance to drop their Lee Sin. Discarding Lee Sin can slow down their game plan by a lot.
  • Once you’ve planted enough Poison Puffcaps, Ava Achiever along with a Corina, Mastermind can deal a lot of damage, your opponent does not run removal spells to take out Ava Achiever.
  • Stress Defense is usually saved to stall the game, if your opponent goes for the one-kick combo with Lee Sin, Stress Defense can stop the incoming damage.
  • Keep in mind your opponent runs Deny and Nopeify! that can deal with Corina, Mastermind and Insider Knowledge.

Mulligan for: Teemo, Caitlyn, Puffcap Peddler, Lecturing Yordle.

  • This matchup isn’t aggressive early on, you’ll have time to set up your Poison Puffcap engines and start planting mushrooms in your opponent’s deck.
  • Your opponent does run a lot of removal tools, cards like Poison Dart, Death’s Hand, and Ravenous Flock can threaten to remove important units on your side of the board.
  • Wait until turn 7, or turn 8 if you have the attack token to play Aloof Travelers. This will increase the odds of you discarding their The Leviathan. If you have more than one Aloof Travelers in hand, make sure to play both of them before they have the chance to play Leviathan.
  • Teemo Swain does not run any healing cards, the damage you push in with your units or from the Poison Darts can be valuable later on in the game.
  • On turn 8 they’ll be looking to set up their Leviathan along with Swain to lock-stun your board – start activating your Poison Puffcaps with Corina, Mastermind.
  • Hold onto your Insider Knowledge until you’re certain that this is the decisive turn. You can play Insider Knowledge if you’re running out of value in hand as well.

Mulligan for: Teemo, Caitlyn, Puffcap Peddler, Lecturing Yordle.

  • Try to kill Jayce before he gets to level up. Your opponent might opt to go for the Challenger keyword on Jayce to remove units like Puffcap Peddler and Teemo.

Mulligan for: Teemo, Stinky Whump, Caitlyn, Puffcap Peddler, Lecturing Yordle.

  • If your opponent goes to remove your Ava Achiever with a Darkness you can play Insider Knowledge in response to force card draw and double the Poison Puffcap damage.

Mulligan for: Stinky Whump, Caitlyn, Puffcap Peddler, Lecturing Yordle, Mystic Shot.

  • It’s difficult to deal with your opponent’s burn plan once they’ve dealt enough damage to your Nexus.

As for Decimate, the only way to deal with it is by playing Aloof Travelers and discard it out of the opponent’s hand.

  • Your opponent doesn’t run ping spell removals, so value blocks are important for you.

  • If your opponent played a Predict card and is setting up for an attack, playing Aloof Travelers or Veteran Investigator can potentially ruin your opponent’s plan to lurk a Rek’Sai or Pyke.

Closing Words

Teemo Caitlyn isn’t a popular deck in the current meta, it has a lot of unfavored matchups but it’s an enjoyable archetype to run if you’re a Teemo fan.

The Bandle City region offers a lot of supporting cards for your Poison Puffcap plan, although it lacks the defensive prowess the old PnZ Freljord version offers, it compensates with the mushroom engine package.

The deck can sneak in wins with Poison Puffcaps, Ava Achiever feels so satisfying when it doubles the damage of your traps!
