Tips for Poopy?

As for why she breaks Rivens and Yasuos, it's actually because people who don't know her don't realize more dashes is a good thing for her. As you should know, her W only stops one dash per champion. Sounds like that means she's weak against enemies with multiple dashes, right?

Couldn't be further from the truth. The thing with most champions with multiple dashes is that they either have to or want to use them in quick succession. For Riven, Lee, Renekton, etc. they have to either dash again or wait out both the timer for a second dash and the cooldown. For Yasuo, Irelia, etc. they're so used to dashing repeatedly to dance around opponents that if they've started their dash spam they're easy to catch during it. So it's actually much easier to get the W off on them than a champ with only one dash, who can either wait it out or even bait it. And of course it's only good for the speed boost against champs with no dashes-- which was nerfed not too long ago.

As for the rest of her kit, using Grasp with your shield toss is a pretty basic tip. And it bounces kinda like a cross between Draven's axes and Zac's goo, based on your movement but also in such a position as to give the enemy a chance to step on it. It will return directly to you, like on a unit kill, if you hit any of the plants with it.

Get used to the range and angle on her E so you can get people on even the smallest terrain corners. But in a pinch remember you can use it to dash to enemy minions and monsters over walls. And if you have a Veigar on your team, you can slam people into his E. (though it won't deal your slam damage since it's not terrain)

Her ultimate can be used to stop incoming ganks, and paired with her W makes the enemy jungler almost a non-issue. Don't go for the full charge if a partial charge will be enough get them off you or an ally. And remember that not too long ago they made it so the snap cast doesn't make the enemy untargetable, so it can be used as a normal knockup too. Greatly increased her ability to CC in a teamfight. Just make sure you don't knock away an enemy that your team could otherwise kill.

People normally do a full tank build on her, even though all her recent changes have been nerfs to her defense scaling and buffs to her AD scaling. So I personally like to do Triforce, but with a sunfire buff coming up that'll likely be better.

i have over 200000 mastery points on poppy. Against yasuo he has alot of damage. take after shock with Demolish conditioning and revitilize. Secondary i like triumph and last stand. works v trynd aswell. you could play her bruiser with cleaver into gauntlet triforce into steraks. Against all the lane bullies, shes pretty hard to play top now sadly.
