Is there any way you could give us the lists of minor clashes?

you mean all the decks used every 5 hours?

Yes, but if it's too much work I wouldn't worry about it. It would just be interesting to see what is doing well in the MCs.

Just being able to see the final decks would be cool too.

heres a deck i'd been using for a while to win clashes, im working on a new deck now though because the balancing changes hurt this deck a lot.

Just curious - where's 4th place deck?

My last version of GC deck was without any Restore Nature's Balance.

Huh... not sure why my deck wasn't posted. Here's Sunyaku's 4th place deck. I even gave it a name. Given enchantment abuse during the qualifying rounds, I assumed players might be playing lots of enchantments, OR would be playing to play against enchantments... so I was hoping to make some of their cards useless with some enchantment destruction, and no enchantments of my own.
