I think it's time we start trying to build a Beast Druid deck. When I saw Mark of Y'Shaarj, I immediately thought it'd be a great addition to the deck, since it kinda lacked card draw. The only real big thing it's still missing right now is a good 1-drop Beast, but I think they will release one in WotOG. It's still possible to Innervate some 3-drop out on Turn 1 tho, which you can follow up with the Mark for some card draw, and a really strong early board. One card I immediately think of that counter this deck pretty heavily is Freezing Trap, but I really don't know what they're gonna do with Secrets now that Mad Scientist is leaving Standard...
Anyway, I hope you guys find this Beast Druid deck as interesting as I do, and I'll keep updating it when new cards get revealed, or if you suggest some other cards that could fit the deck better.
One other card I find pretty interesting for Druid is the Djinni of Zephyrs. I can actually see a Buff Djinni Beast Druid rising too, with Mark of the Wild, Mark of Y'Shaarj, maybe one Mark of Nature, and some Beasts and the Djinnis. Maybe will try to make one of that kind too.
Thanks for reading and cya!
