Reid Duke's win at Grand Prix: Nashville was a wild ride for everyone but the eventual victor. The new draft format has proven to be a tough nut to crack. Wizards has been pushing card quality since Shards of Alara, and the new reality is that your drafts are going to play more and more like Constructed matches. To that end, our first tip comes from Reid's interview with Rich Hagon.
Adjust for real life play by becoming more aware of your draft.
Reid discussed the transition from online grinding to success at major tournaments, noting especially that the fact that MTGO tracks your picks and can even display your curve can make for awkward situations in live drafting.
Understanding the role that different options can play in your deck can be the difference between a 3-0 or 2-1 and a 1-2 performance. Practice making the right decision in the moment, but don't fall into the trap of missing out on a curve-filling choice because you are attracted to the shiny rare or uncommon.
Silverchase Fox is probably worse than Smite the Monstrous, but if you've already filled your four-drop slot with Inquisitors, Mausoleum Guards, and Sentries, you might need the body. Similarly, if your deck is comprised mostly of token generators, having the Fox might get you out of a sticky situation when you face down a surprise Curse of Death's Hold.
To re-iterate, Reid Duke credited his ability to adjust to memorizing the relevant cards in a given draft as one of the most important steps he took in becoming a more complete player. You can do the same.
