This deck is all about probing for magic archer vallue. Try to use your miner, wallbreakers, and spear gobs to pressure and force out something that you can get magic archer vallue. Use your tornado and log to ensure your magic archer is lined up with the tower.
The miner is the main win condition of the deck. Try to be unpredictable with your placments but also make sure your opponent doesn't get an easy king tower activiation.
The magic archer is the secondary win condition in this deck, sometimes you will get more damage with him than your miner. Make sure to have your protractor in hand at all times to make sure you are lining up his arrow to get huge connections on the tower.
Valkery is the main defensive unit in this deck. Rely on her heavily to deal with swarms and ground units.
In the early stages cycle miners spear gobs and wall breakers to figure out your opponents deck and chip away.
In the later stages you want to do everything you were doing in single elixir but be much more agressive with the magic archer. You can drop towers easily with good magic archer geometry.
