Best team comps with Ivern? (fantasy or competitive)

Fantasy Top: Darius Jungle: Rengar Mid: Heimerdinger/Ryze/Morgana Bot: Jinx/Tristana Support: Ivern Darius because Ivern's Q gives him a free dash to the target, giving him free reign for Hemorrhage. Rengar because Ivern's bushes can be placed anywhere for Rengar's passive to use. Heimerdinger because 1) I think bushes hide turrets, and 2) because he sets up obligatory zones which gives Ivern time to reset his cooldowns, not to mention his bushes help Heimerdinger against Marksman aggro. Ryze or Morgana because of their Roots, which combined with Ivern's Q makes for great CC in teamfights (also Morgana's E helps against spell effects which gives Ivern more breathing room). Jinx or Tristana because of their abilities to snowball, and with an easy-to-land Root it becomes far easier for the hypercarries to burst down their opponents.

Competitive Top: Rumble Jungle: Ivern Mid: Yasuo/Ryze/LeBlanc Bot: Caitlyn/Jinx Support: Janna Rumble because of his natural abilities in a teamfight (I haven't played much Rumble but I've seen how tanky he can get, and his Ult's Slow should give enough of a window for Ivern to land his Root). Yasuo because he'd be the Melee Carry that most benefits from Ivern's Q (he can dash to his opponent, Q them, W any retaliation, and keep shredding his opponents down until he gets his Penta). Caitlyn because her Attack Range and traps combined with Ivern's abilities (as well as her being in a makeshift bush) is just overpowered for teamfights. Jinx for the reason said in the Fantasy pick. Janna because she supports Caitlyn very well and she's very disruptive in teamfights (her Q is perfect for Ivern to land Qs as well).

This could belong in Concepts and Creations, but I put it in Gameplay because everyone's in the middle of brainstorming what Ivern can do with his abilities and having a comment thread there specifically made for testing just how powerful he'll be with team compositions is something good in my books. So what teams are you going to think up? List them here and let's see just how broken we can make him.
