I am really looking forward to the revival of Brawl in the Fall. In the meantime, here is a current brawl deck in the now dead format. There are more than enough Goblins to make this deck, but there is only one Goblin lord, and a four-drop. I used artifacts from Ixalan block to get some benefit out of running Goblins, yet that's not enough. The Krenko effect can go into some other deck, and that other deck does not need to have any other Goblins. This deck is the epitome of a linear deck: attack with Krenko after making him as big as possible; make more Goblins; win.
These screenshots don't require much of an explanation. They are all about boosting Krenko.
It's nice to fetch more Goblins, but with only one lord in the deck, all of the other Goblins are mostly decorative in this deck.
Krenko can be boosted with an instant. Why not!!
Vanquisher's Banner is the second lord of the deck, but it gets set up even later than Goblin Trashmaster.
Don't you love all those Goblin tokens!?
