Hello,
I found a mage tempo deck that works well with the default aggro config.
It requires low decision and generally works with: go-to-face.

There is only 1 card that should be changed in a custom config.

I believe, this deck would be a real option afterwards to help us all to get rank 5 in standard.

The card is the legendary weapon Aluneth (6 Mana 0 ATK 3 Dur).
I found the card ID: LOOT_108

And I found the commands:

InHandBonus

my_hand(count())

turn()

sum(cost)

However, I fail to create a valid .json file.

The logic is:

if LOOT_108 is in my_hand
then
if turn() >= turn 6
then
if sum(cost) of my_hand + hero_power - Aluneth(6) is below turn()
then
must play Aluneth

In words

If you hold Aluneth in turn 6+(Turn) and you have other cards (>=4+(Turn)) + hero_power(2) with value to complete a turn, Aluneth does not have to be played.
But if you have Aluneth in turn 6+ and your other combined value is below cards+hero_power(2), then Aluneth must be played.

Would appreciate if someone can create a valid LOOT_108.json for this.

I can share the deck, of course.

Best regards,
