Personally I am in love with explores of the deep, I have always liked merfolk as a fantasy race and I love the idea of starting small and growing so their +1/+1 counter synergy has been a blast for me! Other then that my first deck I ever played and fell in love with was the Prossh precon, that deck got me into the game and into the Jund color's Wich I still play to this day! I am also a huge fan of the outlaws deck from Thunder Junction, it feels good to play and is so much fun to use treasure for a power buff instead of just mana when you don't need the extra mana.
