I love Vanquish Souls. They are such a fun deck and you can climb with them for sure. You just have to have the right balance of elements in the deck. There is a slight learning curve but its not as crazy as other decks, and it feels to good when it starts to click. And its pretty non linear in that even though you may be doing the same combos its never the same route/line every game.

Snow Devil is a crazy card. Its won me duels on using it correctly. We are in a format that doesnt have as much destruction protection let alone non targeting protection. Can really stagger or out right stop an opponents turn. Jiaolongs search is disgusting. Its a quick effect and can be done on both players turn for a whole archetype search (including spell and trap cards)

Edit: Also how could I forget. Stake your Soul! Your Nose is Mine! Stake your Soul is the most ultimate card to claim your opponents nostril and instantly win the duel - Milano, pro Yugioh player.
