I'm a former TCG player and YCS winner. I know people are both shocked and disgusted that Sylvans took the MCS this weekend, but I wanted to give some people perspective into why I chose this Deck from the mind of a competitive Duel Links player. I love unconventional strategies (meme Decks) as much as everyone else, but this is the Duel Links tournament with a $2000+ prize pool and I wasn't going to play anything I didn’t consider the best Deck.
My Main Deck was incredibly standard. This is the Sylvans decklist that was standardized by Billy Brake with the single copy of Loading.... I was originally running triple Loading... instead but I found that it was better to draw 1 Tribute to The Doomed and 1 Enemy Controller in most scenarios than 2 Enemy Controller. Tribute to The Doomed was also a way to get Loading... into Graveyard without committing a Normal Summon. Because the Sylvans core takes at least 16 slots in your Deck, I believed these to be the 4 best Spell/Trap options for the metagame.
