To add what DM says,
Typically, one should not claim any validity to a deck and make a post without at least a 15 to 25 game run.
Even then a 15 or 25 game run on some decks I've posted, just had 'new deck luck'. It has caught me a couple times, I redacted at least one post here because of it because the next 25 games where so awful, something showing 80% suddenly falling to 30% WR, so 50 games is more ideal.
If you truly want to catch someone's interest post that stats with the 50 games.
Then it takes 100 games from another person doing it over in the stats area in order to find where your deck places before one really get's to claim the best HB ever.
Also note,
There are many decks that do 4 TTW once and a while, even 3 TTW
There are many decks that have a < than 7 Average TTW
Finally, the current 5th ranked and many a bit below that, which have close to similar stats don't even use shards.
So is your deck the best, maybe, it'll probably be a top 10 by the test for a while given the efficiency bravery gives.
However, your deck has a lot more weaknesses than those top 5,
all have cards that can counter a bravery and or nova or a 150 OTK, which your deck depends on.
