This item is either useless or highhandedly wins the game based on whether it picks a carry or not. Losing purely off of zephyr's dice roll picking your most important unit feels like absolute shit because there's nothing you can do about it. The final fight between first and second shouldn't come down to zephyr rng.
It isn't RNG which Zephyr uses to pick a unit. I'm told it picks similar to a blitz hook, and by positioning/counter-positioning, you can keep your draven from getting hit.
So 
picks the target that is most closely counterpart to the champion holding the item. So if you put him in lower right, he will Banish the upper left.
I think Zephyr should stay in the game BUT be changed, it needs to pick a Neutral(mid-powered champ) you should NOT pick the Weakest enemy and also should not pick the 3 Item, 3 Star Garen either. Again as stated in many posts, this game is based on Luck. Little strategy as I was hoping for.
If your team dies in 5 seconds then your team is bad....its nice to build around a character but typically people have strong enough tanks or a 2nd carry to make up for 1 guy getting ccd or killed.
basically how I feel about phantom effect
Zephyr takes the adjacent symmetrical enemy unit. Positioning and counterpositioning become important.
The only item that needs to be reworked in TFT is Force of Nature.
