Hi,
this is a quite good team combo, which is an instant win if played right.
Malphite can make a good ult to let wukong and zyra follow.
Yasuo should make his ult as soon as he gets the most people and MF should try to get as much people as she can aswell.

I pref these Zyra-items for a few reasons.
With your distortion upgrade you can make flashgages (flash-engages), to catch someone with your e out and follow with a good placed ult, so yasuo can follow.
You have enough magic penetration through liandry's and the boots.
Talisman gives you a good engage tool, in most cases malphite or wukong will try to engage and this speeds them up.
Zhonyas will make your flashgages quite more effective and rabadons gives you a bunch of ap.
I also like the effect of Liandry's.
These 3 Randuins make them really slow, it doesn't matters who engages, the two others of these three Randuins-owner (yasuo malph wukong) will be able to follow.
Malphite has a good slow with Rylais and quite a good bit of damage.

You can make several engages:
1. Zyra flashes, gets focused, ulti and zhonyas by her, team follows.
2. Wukong goes invisible, makes ult and randuins and team follows.
3. Malphite gets speeded up by zyra, places ulti, wukong follows, team follows.

I'd love to get comments :)
