The series was a lower bracket series, meaning the losing team would be eliminated from the tournament.
In the first two games, Muerta was ignored completely neither picked nor banned.
It was a position 1 Muerta to be played by their talisman, Artour Arteezy Babaev.
Shopify Rebellion defeated Tundra 2-1 to make it to the top 3 of DreamLeague Season 19.
Gunslinger works on buildings as well!
So how did Arteezy choose to progress on Muerta in terms of skills and items?
He stopped Dead Shot at level 3 and maxed out Gunslinger instead.
That can have its benefits, especially if you have finished Maelstrom early.
In his case, he got it at 12:34, which is a very good timing.
Later in the game, he sold it to replace it with Eye of Skadi.

Muerta also got a huge indirect buff with therelease of Dota 2 patch 7.33.
BKB no longer blocks all magic damage just 50% of it.
The second major buff, which Arteezy made use of, was the introduction of an Aghanims Shard upgrade.
That is around 28% of the total damage dealt.
