Going to start my first card review off with an obligatory "awesome Liiga art" comment.

More seriously I think anarchs may splash this over Mimic in Leech builds as at least a single copy. It's only 1 inf and you won't get blown out by a Cyberdex Virus Suite into an Anansi or Surveyor as it can still get pumped up, and matches mimic strength once the runner is set up.

On the shaper end, I don't think this will be slotted while Na'Not'K is still legal, and Adam still prefers Odore.

Late-game, this is crazy-efficient. If you are setting up towards a Conduit win and can afford to spend 5+ turns setting up, a 3-strength Echelon is roughly as efficient as Bukhgalter and a 5-strength Echelon is one of the most efficient killers there is. With DZMZ Optimizer, we have some of the pieces available to make a huge rig work. But corps have great high-tempo options currently, and Echelon generally won't help create early pressure. For a lot of the game, Echelon matches up very badly against the most commonly used sentries (Drafter and Turnpike, both strength 3). Until you have 3+ breakers out, Anansi costs 9. Brutal.
