[Primer/Deck] Pox

[Mr. Safety]

I think Lost Legacy would be fine against Sneak/Show, actually pretty good. I just don't see the matchup very often. I would definitely want 4x Dark Ritual if I were to lean on Lost Legacy. Sneak/Show is actually very weak to targeted discard. They aren't a t1 deck, most likely a t2-3 combo. Cabal Therapy is very good against them, just name Show and Tell. Targeted discard + Surgical Extraction is also really powerful against them. If they have the nuts, then they have the nuts. Sometimes they are just unbeatable. Pox does have some really good cards against them though:

1) Thoughtseize/Inquisition/Therapy: grab/name Show and Tell 99% of the time.
2) Wasteland: kill their Ancient Tomb/City of Traitors, it will slow them down by at least 1 turn.
3) Liliana/Smallpox/Innocent Blood: sacrifice effects are very good against Emrakul, can be mediocre against Grisel because you know they are digging for Force in response.
4) Pithing Needle (side): name Griselbrand 99% of the time, unless they have a Sneak Attack on the battlefield then it might be correct to name that.

A likely better option is to play Ensnaring Bridge in the sideboard. Bridge is classic tech for Pox decks and pairs up with Bitterblossom in a huge way, it's basically a combo-lock against anything using the attack phase to win. I also like the Helm/Leyline line of attack because Show and Tell lets you put in Helm for free. If you see the matchup a lot, Fleshbag Marauder is pretty good tech against them. Bontu's Last Reckoning seems to be ok as well, but not sure how good. Others would have to pipe in on that.
