Cong "StrifeCro" Shu is one of Hearthstone's most revered players, known in the scene for both his deck building skills and absurd critical thinking abilities in the game's constructed mode. His stream is one of the most helpful you can find, as Strife carefully walks through the rationale behind every single decision he makes.
Strife switches up the decks he uses on a near daily basis, which gives viewers a bird's-eye view of the Hearthstone meta. And since they get to see what it looks like to pilot all the most popular competitive archetypes, it's an easy way to start understanding the game from the opponent's perspective. On top of that, Strifecro might be the most chill streamer on this list; sometimes his reactions are so mellow that you might feel the need to rage on his behalf. But hey, consider that supreme poise something to strive for.
