What's your best sideboard card all weekend?
Nam Sung Wook (Pro Tour Journey into Nyx Finalist): I am playing Jund and I love Surgical Extraction. I was able to surprise a few combo players by removing their key card.
Don van Ravenzwaaij (Australia Pro Point Leader): Cavern of Souls. It was good against the sea of blue decks this weekend!
Shota Yasooka (Pro Tour Charleston Champion): Jund. Night of Souls' Betrayal is my best sideboard card.
Lee Shi Tian (4 Pro Tour Top 8s): Blood Moon, of course! It's like my trademark card now. I'm playing Grishoalbrand.
Leong Ding Yuan (World Championships 2005 Top 8): I'm playing Boros Burn and the third Grim Lavamancer was awesome. I played against 4 Merfolk already!
Ken Yukuhiro (Pro Tour Avacyn Restored Top 8): Stain the Mind. I am playing Next Level Abzan and combo decks are bad matchups.
