Solidarity Badge is like a Chop Bot 3000 crossed with Friday Chip.

If you can trash a Corp card each turn, then you'll draw a card each turn (cf. creds for cards).

Note: While clearing tags at the start of your turn is worse than at the end of your turn, such as after encountering an observer, it will still clear any terminal tags (or tags you've floated); and it still saves the [click], [$2] basic-detag. For example, if you've trashed their card, they can Oppo Research, but you've also “charged” a Badge, which then can remove one of the four tags (before they can punish it).
