@Aelien good questions and thank you for the reply. I played many years Storm Deck like Gush Tendrils, TPS (with Bob and less), Long or Doomsday, in Italy our meta is invaded by disruptive deck imprinted to denial. 14 is the right number of lands - in my head, obviously - to stabilize Storm. The great number of MUD push me to play a solid mana base: 2 island and 1 swamp to optimize the effect of fetchlands.
4 discard effects are the good number: not always we lose life, misstep is present in the meta and the fact that it's played on a Duress or on Thoughtseize is better than seen it on Ancestral Recall. The second discard effect is the best we can improve, specially against MUD or other creatures deck (all decks play a great number of those). This is also the reason why I play 2 Fatal Push in main deck. Hurkyl's doesn't resolve always all problems and I'm so scared from Team Leovold, maybe I can pass to 1 but for the moment I'll stay so.
DP is a good card but I don't like expensive spell: in this deck we have just 3 YB, Desire and the most control nature of my list doesn't allow to have always an exploding start. Grim Tutor is perfect for me because after threshold, all rituals become istant closing.
A most controlling shell, with 8 protections, allows us to play against all decks without risking to concede at an earlier date.
A question, playing my list which cards would you take away and which you suggest?
It's hard to take seriously someone who is advocating grim tutor over dark petition, and playing 2 creature removal slots md. Grim tutor is 2 mana and 6 life more expensive to set up a yawgmoth's will win and a lot worse at setting up necropotence or other bombs. It's also a pretty bad tutor to be using with yawgbargain. Creature removal seems really bad unless 90% of your metagame plays hatebears maindeck and even in that case you would want a boardwipe like massacre/Toxic deluge or a plan b like tinker blightsteel/pack rat.
