This is the deck i used to reach rank 1 legend on EU. I reached it on the 3rd of november but lost it on the 6th.
card you always keep without coin: Dragon Egg
when to keep Power of the Wild: with double 1-drop+coin and/or with innervate and low cost minions.
all other cards are irreplacebale imo.
If you have some questions about the deck you can add me on eu ( darkshadow#2303 )
Shoutout to J4CKIECHAN for introducing me to egg druid and defining the best 25 cards of the deck. You can find his deck here: http://www.hearthpwn.com/decks/323471-j4ckiechan-egg-druid and his twitch here.
Have fun trying the deck :)
