Hello all; I have a question about what I think is the "contain" defense token used with the MC-80 and the ISD. I don't know if I'm blind or what, but I can't seem to find anything explaining it, and I hope someone can tell me exactly what it does? Thanks, Steiner

There's a blurb in the pamphlet that came with the ISD, and presumably one in the MC80.

Basically you spend it to prevent the default critical effect. Keyword here is default. You can't use spend it to prevent critical effects from upgrade cards such as ACM, XX9, APT, etc.

You spend it to let Needa give you an Evade token instead.

Yeah, real easy to miss that the piece of paper with the expansion packs "list of contents" also includes some game rules, I very nearly threw mine out.

As mentioned, the contain token will prevent the default critical effect from giving you a face up card. If your local meta uses lots of upgrades with critical effects, not very useful, if your opponents focus more on raw damage than crit effects, it can be a life saver (because a lot of the crits in this game are just HIDEOUS).
