I think as a single shard, invention would be pretty cool for me. Invention just fits pretty well with my skillset/interests.
As a hybrid, I think Invention and Whimsy would be awesome together, again, it would align pretty well with my preferences. If I were to be a super hybrid of more than two shards, I think I would add valor to that, maybe preservation too.
If i had to choose though, I'd rather not have any shards at all, I would not want it to mess with me as a person, and I just don't want to have that much responsibility/power
