Hi guys!
Thanks for the congratulations. I'm currently moving so I don't have much time to play, but I'm always glad to give some advice.
Lol I don't know about the "famous" part, but yeah I know Jaytron from various Legacy twitch chats.
I think you board partly wrong vs. Shardless:
- Pyroblast is ok against them (though I don't like more than 1 tbh because you already have 4 stifles to stop ancestral visions). I wouldn't necessarily want more than 1. Before getting a second I'd rather keep an additional FoW for Toxic Deluge or a big threat.
- Pithing Needle and Ancient Grudge are some very very narrow cards. You already have more than enough stuff to answer Strix and Agent and Pithing Needle is quite bad because:
1. when you play it out before Liliana resolves your opponent just doesn't play her and brainstorms her away, leaving you with card disadvantage. If he really wants to push it through he's gonna Decay the needle eot anyways and then play his lili.
2. when you play Needle after Liliana has resolved you already have sacrificed a creature (which can be game-losing if it was e.g. an Angler).
The main way to play around Planeswalkers really is Daze and Stifles (e.g. stifle the sac ability) mixed with YP-tokens. Planeswalkers really aren't that good against this build and I really wouldn't want a specific answer to them.
The way I board is bringing in Grim Lavamancer, Forked Bolt, Fire Covenant, 2 Decay, Surgery and Pyroblast, taking out all the Probes and Forces (you can leave in like 2 otd cutting some Dazes). Especially Daze is really good in this matchup because Shardless can't really afford to play around it all the time. They tap out pretty much every single turn to play the most game-changing thing and our task is to prevent their 2-3-4-mana investments by our own 0-1-2 mana responses, gaining tempo. Also we have slight card advantage via Grim Lavamancer, Fire Covenant and Young Pyromancer plus the fact that they have to play out all their lands while we can operate on 3 (if you play decay, 2 if you don't).
Dredge is hated out rather easily tbh, just put in 2-3 Surgical Extractions in the sb (though I'd say 2 should be enough). For D&T I like Dread of Night or Grim Lavamancer (the last one especially when they're heavy on Sanctum Prelates).
I don't like Stifle vs. D&T, you should cut them for Therapies (they reveal cards to you with Stoneforge and Recruiter). Removal like Grim Lavamancer and Forked Bolt are key in this matchup, but so are Pithing Needles imo (Mom, Rishadan Port, Vial, Equipment).
The best answer to TNN are really Pyroblast and Daze, often times it's also not that big of a threat when you have a board that can race it. The nasty things with TNN really are the equipments, but once you get rid of them post-sb it should be not that much of a problem.
When you lose to cards like that ask yourself if you'd lost to any big spell they could have (Lingering Souls? Mentor? Jace? Angler? Goyf?). Chances are you already were behind because you e.g. couldn't prevent them from getting enough mana and not threaten them with creatures early on. Losing to TNN is really just the nail in the coffin, but not the specific reason you lost there. I lost to TNN a fair share myself, but almost never when I was ahead in the game.
