Step 1 - Play a creature with countdown 1.
Step 2 - Pump it!
Step 3 - Profit.
Of course, there are a few subtleties to this deck, but the main idea is there. Play one of Kinfolk Brave, Owl, Earthborn Keeper, Wildling or Wetland Ranger, make it big with Stag Heart, Champion Ring or Earthen Mirth, and never let your opponent take control of the game by killing his or her units as soon as they reach the board.
Kinfolk Brave, Owl, Earthborn Keeper, Wildling, Wetland Ranger
All creatures with a countdown of 1, that you want to play early, pump so you can kill all opponent's threats, and protect so you don't get 2-for-1'ed (or worse).
Stag Heart, Champion Ring, Earthen Mirth
Pump your creatures with CD-1 so they become dangerous. Try not to put too much on one creature so you can't be screwed by a removal.
Here are some of the niceties of this deck.
A good way to defend your important creatures, and it pumps them at the same time. Really one of the most important scrolls of this deck. Don't hesitate to put them in the front line, it's better to loose a Mystic than to loose your enchanted CD-1 creature.
To be discarded almost all the time versus any Growth deck, this is probably the best card of the deck against Energy, Decay and Order. This deck looses a lot to things like Burn, Soul Steal or Pushback, so it's important to prevent them from doing that on your pumped creature. Might be good to add a third one, depending on the meta.
Vaettr of the Wild
As in every Growth deck, it allows for explosive starts. Turn 1 Vaettr, turn 2 Wildling, turn 3 Earthen Mirth is pretty unbeatable.
Leeching Ring is a scroll I added recently to this deck, and it truly shines here, especially with Wildling. Play a creature next to your Wildling to pump its strength, and regain the toughness immediately.
Ragged Wold, Kinfolk Veteran
Those are here for the surprise factor, and because they just are strong Growth scrolls. Doing Ragged Wolf + Earthen Mirth can sometimes kill an important opponent unit but that's quite rare, it's often better to make profit of that enchantment on a CD-1 creature.
I'm not too sure about those slots, they could easily be replaced by other things. I'm open to suggestions!
Sometimes help winning a game by unprotecting important opponent creatures.
Sometimes useful to finish an idol and clear a line. It's not the most important scroll because you get to pump your creatures with enchantments anyway.
Vilda the Verdant
Just a one off because it's Unique, and I'm not a huge fan of it. It fits nicely in the heavy enchantment theme though.
Because it's relentless and can sometimes do great things with a timely Earthen Mirth. Could be replaced with Gravehawk, but I think the 4 toughness and the optional 4 strength make it a better choice.
