Best Ultimate/ability combos between heroes?

After this post on reddit, we see a combination of Mei's Ice Wall, Roadhog's Whole Hog and Widowmakers Infrasight. This play caused the enemy team to become trapped and die at a choke. Obviously ultimate cohesion is a big part of the game, but there doesn't seem to be a thread about it here yet. Post your thoughts about what Ultimates would work well together, or what you have seen from first hand experience if you're one of the lucky bastards that got into the beta

zarya's ult and everything:
everything

d.va's ult and hanzo's ult:
Use d.va's ult to force people into hiding spots (hopefully inside of buildings) and then hanzo dragon the shit out of that building

IMHO widowmakers ult is REALLY good with pretty much everything, because if people survive the initial attack, you can always clean them up easily because you know exactly where they are.

Reinhardt ult into Mei ult is really powerful. Anyone he knocks down is basically under crowd control effects for the next 15 seconds. Throw in a Reaper ult at the end and it's 100% death death death.

then a sneaky "oops, this might sting" undoes all your work :<

Not if you catch the Mercy in the knockdown ;p

I personally like countering ults with Lucio's. His ult is very useful against most other ults in the game. Feels good to know you helped your team survive through these ults by timing yours well.
