Thanks to That Resolves for helping me get to Masters! I just started playing in early April so using his list was very helpful.
This deck is a beast.
His description is here: https://www.youtube.com/watch?v=tCyBzpjIC_8
The only change i made was -2
Tamarys, Earthshaker and +2
Bloodlust.
Bloodlust outright wins the match so often, and is especially good against all of these Tasbu decks running around, you get 12 damage, avoid giving them a draw and dealing with his deadly until you get the removal or just win. The combos can get ridiculous with scream//last chance/berserk/rapid shot. Don't forget to count Nightfall and Instigator face damage when calculating lethal! You can get some really creative lethals with this deck very early.
Open to all suggestions!
Bloodlust really paid off for me in at least two of the 10 games I played between D1 - Masters and I agree that the original list had too many Tamarys.
I imagine he was probably dealing with a lot of relic rat/jishu/token decks on the original list but I'm happy it's worked well for you. I find it still does pretty well as is against those aggro decks as is with all of the lifesteal available.
Please let me know if you think of any other changes to potentially improve it further!
