I've been grappling with the dichotomy between wanting to help newer players and not wanting to hurt myself as well as my brother's in arms. The past 8 years have seen me learn, grow and evolve as a Workshop pilot. I could not have gotten to the place where I am now without the help of others and so I feel an urge to spread the good word of Mishra, but I don't think posting on TMD is the best medium.
I have spent countless hours thinking about Workshops, tried some really awful ideas out and obsessively focused on my sequencing, mulligan decisions and sideboarding. The problem is that by sharing my insights I may dull the edge that I have sharpened because anyone can read what I or anyone else posts, Workshop pilot or not.
While I don't want to give up my advantage, the bigger thing to me is to not give up the competitive advantage that my friends have created, especially when I am still borrowing some of their technology. A lot of the secrets I have found are not mine to give away.
My general advice to someone getting into Workshops is:
Understand why you won and why you lost. If you're consistently losing to the same thing or things, you need to adapt.
Don't get complacent. Even if you think your deck is 75/75 perfect try to anticipate the next change and go from there.
Workshops are a hate deck. If you don't know what you're going to be fighting it's hard to make sure you have the right tools.
Pay attention to as many of the details as you can. Understand what hands are winners and what are losers, analyze the sequencing of your plays and look at how you physically respond to your opponent and try to mask your emotions. Goldfishing is great for getting down the sequencing and mulligan decisions.
Practice with people who are better than you.
Understand exactly how to sideboard for every matchup and tweak your plan based on the games you play.
