What's the most innovative deck you've ever seen?

Not just innovative as in an unusual/refreshing strategy, but I also mean *powerful* - not necessarily in a cEDH meta sense, but in a sense that it does its strategy in a very effective and clever way.

I've seen a really fucking cool Zur Cycling build... not necessarily OP like a cEDH zur but super flexible and effective at what it does with tons of clever synergy.

Lemme know what you've seen!
