I feel I need to play a few drafts where I actively count how many permanents end up on the battlefield. I don't think that I reach 10 particularly often, but then again, I could be wrong. I also have no idea which particular types of decks get to 10 in my list. I don't think my aggro decks go wide enough, but I suspect that my artifact control decks might get to 10 in the late game, but none of the effects spoiled thus far really fit into that kind of shell.
In lower power lists, with artifact support via clue, treasure and servo tokens, getting to 10 might be more viable. Something like an anthem which offered +2/+2 with the Blessing, and +1/+1 without might be interesting in such a shell, but unfortunately in this tribal block, Glorious Destiny, which only pumps an individual creature type will likely be the closest we will get.
