If you did that on purpose, you're extremely lame.
Take a look at this guide. it's very detailed and helpful: http://www.solomid.net/guides.php?g=59898-scghost-poppy-build-guide
The point is to buy and spec your masteries towards sustain and abuse your passive. Rejuv Beads and potions are extremely effective on her because of her passive, so a lot of the time you rush Hydra, and depending on the lane, you can grab a Sheen before finishing your Hydra, and sometimes before your Tiamat.

something I noticed in that guide is he said to ult the ad carry. I thought you were supposed to ult the support in team fights?
Ult ADC if your team is competent, ult their champ with the least CC outside of the ADC if you're in hard carry mode.
The 2 games in my match history were the latter. First one I'd let Sona blow her ulti then ult her and kill everyone else. Second game id let noct ult us then ult him and waltz by him to the back line.
