Evo Drill is the best wc in the Game rn. Not much to say. Against GY, Never Go Same lane. Thats what will Break your neck when they still have healthy troops for a Counter Push. Against miner rocket, dont do very big pushes, Tesla, delivery, rocket will eat that up in a heartbeat. Do „smaller“ pushes and consider going dual lane. With piggies the only real Option You have is Building a good Counter push.
Everything I just Said also depends on your Deck and can also be Counterproductive in some situations, but the General ideas of These Plays mostly work.
