Hello, this series is a good start. “Trump’s Basic Teachings”
This is also a good one.
Knowledge about the opponent’s deck comes mostly with experience, but anyone can analyze the current meta and memorize the cards. There’s a site called HSReplay, it will show you what’s popular.
If you have more questions, or are interested in some free coaching, feel free to add me. freckles#12809
Heh, yeah - they just got wiped out by the change the new forums.
Silverangel has the links above though.
On the topic of Deckbuilding specifically I highly recommend the Deck Doctor series on the Omnislash youtube channel. In it Firebat (the 2014 World Champion) takes a decklist submitted to him over twitter and tries to make it better. He does a really good job of explaining his thought process and why he’s changing what he’s changing and stuff.
Here’s the latest episode:
The channel in general has a bunch of great Hearthstone content so I would really recommend it.
My other suggestion for learning better play it to watch strong players on Twitch - particularly ones that do a good job of explaining their plays and thought processes. My personal favorites are again the Omnislash guys (Firebat, Brian Kibler, Zalae), but there are a ton of good Hearthstone streamers out there.
