This is the Kolento Token Yogg Druid w Medivh Moonglade Portal Deck he was playing on stream to hit legend this season.
Medivh, the Guardian, and Moonglade Portal are two of the cards from the last Karazhan wing. They are a good fit in Druid, and if you’ve ramped to hit these cards early you’re going to have tempo on your side.
The 2 x Ancient of Wars are pretty important right now as the ladder is being terrorized by aggro Shamans. In a more control heavy META you can take them out and put a second Moonglade Portal and Arcane Giant in.
