Are there any guides? And if I find it ?! (The Elder Scrolls: Legends)

Are there any guides for building decks for this game? or maybe fan sites with ready-made hearthpwn decks for hearthstone? The toy is cool, I love kki. But when I saw that there could be as many as 50 DECKS in the deck, then I freaked out a little. I can't even understand how many first drops, for example, should be in the deck? at heartstone, two out of 30 cards are enough. And then as many as 70 cards can be! In general, I would be grateful for a couple of links, or maybe even advice based on my own experience. All top decks!
