I often play strategies that arnt really meant to win, but are fun. Like:
Politics (making deals around the table)
Hug (giving people things and helping your opponents)
Copy/steal (your deck is my deck now, here's some garbage)
Chaos (alright, everyone put your cards in the table. We are gonna shuffle everything and deal them out. Those are your new cards in play.)
I do like wide strategies, I guess those are a playable strat that doesn't piss folks off. I like elf tribal. (Elf decks)
Wide strat( many many small creatures)
