sivir adc with yasuo support possibly as a counter to xayah + rakan bot lane?
sivir's E can block the very obvious knockups by rakan, and yasuo can windwall xayah's feathers, plus use it to counter the very obvious xayah ult + any ranged poke that comes in from xayah. On top of that, yasuo can tank poke with his passive while delivering a pretty strong poke early game with sweeping blade + steel tempest.
core builds for yasuo support being
and 
(and possibly 
)
along with some vital cleansing with 
and 
for cooldown reduction.
for towerdiving as well as more cooldown reduction or switch it out for 
or 
for more health + cooldown reduction
Elixir to buy 
Summoner spells could potentially be
always on hand
+
for kill secure
if you're ballsy and prefer the healing save and think the cc from yasuo's wind twirlies + ult is enough time for sivir to do damage
for obvious reasons
OR
and you can take the occasional CS + build 
with bloodrazor to slow people with the chilling smite (and I don't know why else it just sounds fun)
One huge problem with this could be that unless you get your adc fed, it could fall really hard late game
Anything you guys might think to add or criticize before I buy yasuo and try it?
