Unorthodox builds and scenarios thread (special tactics)

After playing a bunch of regular games I tend to wanna try out a few unorthodox things just for fun.

Examples:

• Axe + Dark Seer behind enemy towers creep blocking
• Ursa + SK level 1 Roshan kill
• Wisp + Pudge level 6 respawn fountain gank
• MoM + Alacrity invoker nuke build
• ... ?

and one I just tried myself:

• Enchantress level 7 solo roshan

I'm looking for new and original stuff to do, so if you know something, please share it here!
