Mei double tank - double wall spam

I wanted to try something different from the coulder meta. Just wanted to be annoying and cause confusion in game with walls. It is a pretty tanky build with 250 armor by round 7. Wall, cryo-freeze (resets wall) then you have wall again. Wall blizzard included because it slows them down enough for the team to secure kills, while still being able to use another wall shortly after cry usage with another blizzard. Just a build I found fun and experimenting with.

You can put [Twice as Ice] round 1 and [Iceberg] round 3 if you want to be annoying round 1
