At the Gencon ~90 man at Gencon 2013 I played 2 x Snare and top 2 split the event with @bactgudz . That was an interesting event because it was Pyromancers coming out party pre champs. This was also pre-Dack, and pre-Delve. The counterspell suites back then (almost 4 years ago ... man I'm old) were much more diverse. The world hadn't homogenized around 4 x Missteps. But the decks that did tended to be the Pyromancer decks, and Delver Pyro decks. This is what truly started the slide to where we are today. The top 8 blue decks from that event played 2 x Pierce, 0-2 x Snare, 0-2 x Steel Sabotage, 0-3 x Misstep ... I also played Mana Leak and a gentleman's Drain. The rise of the token based kill conditions synergize so well with derpstep and to a lesser extent Probe and Gush you are incented to max out. Then dack came, then delve came and there was no turning back from 14-16 free spells and the super light Gush manabase. The synergy was too insane. Anyway, Spell Snare is fine when Pyromancer and Snapcaster were the premier creatures, Oath and Burning Oath were big, and it's always good vs. Shops. But once every blue deck is playing 4 x Derpsteps and Pyro costs 3 instead of 2 and kills you in 1-2 turns it's efficacy wanes. RIP Spell Snare you snared many Spheres.
