Slowly climbing up the ranks in TFT. And I'm back to playing Poppy builds. Not sure why I like playing them but I've found it fairly consistent for hitting top 4 and real easy to add in Karthus in the late game to push you over the top. I have a few options with the build, aim for 4 knights, 2 guardians and then can fill out the build with a splash of glacial, ranger. If you are feeling real dangerous you can go deep and try to hit 6 nobles.
I've had good luck with Poppy get all the items but really any tank would do. Add a Thornmail and Dragon's claw, then buff with guardians and you should be good to go. Depending on how your items go, it's pretty easy to make a statik shiv to add to a ranger or a late game mana item for Karthus.
The meta is pretty diverse right now so being flexible helps me get into top 4 more frequently. I just hit Gold IV after my last game. A ways to climb yet but hopefully my strategy will continue to propel me upwards!
P.S. Karthus is just stupid strong right now
