Mulligans
This deck is built around shuffling cards into your deck, hopefully with augmented elekk on the battlefield. If you elekk on 3, you could play espionage, strider, darkness, or lab recruiter on 4, generating a huge amount of value. you can use witchwood piper to tutor the 1 mana minions you get from espionage into your hand. I thought that pogo hopper would make a good addition as a card that gets stronger each time you play it, but it doesn’t play a key role in the deck. I did notice some combos, like playing the darkness (or just shuffling a ton of spiders into your deck with strider) and then playing Myra’s unstable element to possibly get you a 20/20 on turn 5.
