The closest comparison to Mache is definitely Astrolabe. But while Astro gave you free cards every time the corp created a new server, this card requires you to proactively go trash assets. Not great, as shapers often did best largely ignoring the corps horizontal spam and focusing on hammering centrals, using their shiny free cards. With Mache, you are not getting squat unless you spend your credits and clicks to go after the corp.
The big saving grace with Mache is in the one word it lacks: console. Astro was often played as a cheap way to get 1 more MU, with runners just accepting that it is just a fancy Akamatsu Mem Chip if the corp wasn't going horizontal and being thankful for the cards if they did. But now you can play this AND a fancy console to advance your game plan. Or both this and Astro if you really hate asset spam.
Also, this card will almost never be dead in any match up. Even if you are facing a glacier player with one big server, trashing a couple of NGO Fronts, a Rashida Jaheem and a Crisium Grid is gonna give you a couple of free cards. Unfortunately you need to draw 4 cards off this to have made a profit, which is a lot. If only Kate were still with us, she could install this for free...
In short, it might not be strong enough to warant play, but it is definitely a fun little nugget.
