I am not happy with the name, as Dominion mnemonic suggests that such a card should trash a card and gain another one related in value to the trashed card.
Otherwise I would think that in some boards we'd have a Dame Josephine of ruins that no one wants, such as Library in a kingdom where splitters are scarce.
Is that a comment on this post?
New Looter suggestion...
Restore (Action Attack Looter, Costs 5): Each other player gains a Ruins. Gain an un-ruined card corresponding to one of them. (The card you gain may come from the supply or the box).
And then of course the corresponding Ruin:
Underfunded Restoration: Each player (including you) gains a Ruins.
I agree that Restore is not a good name there; like you say it sounds like it should be in the remodel/rebuild/remake and also not an attack-y sort of card.
The idea behind the card was to make a real link between the 'good' cards and the 'ruined' versions we're all coming up with. Restoring a ruin to its original state.
Maybe we could have:
Restore (Action-Looter, Costs 3): Trash a Ruins from your hand. Gain the un-ruined version of it.
And the corresponding Ruin:
Underfunded Restoration: Trash a Ruins from your hand. Gain a Ruins.
Now Restore kind of fits the remodel/rebuild/remake family (except that it cares about name instead of cost).
