WDC #223: Weak is good, actually!You may have heard me complain about conflating "good" and "strong" before, so let's make it a theme.
Design a card that's in the bottom half of cards in terms of powerlevel. This criterion is not measurable, so I recommend aiming for, say, the bottom 25% to avoid ambiguity. Of course you don't want your card to be too weak since then it'll never be used, so it's a balancing act. I'll try to be lenient but will disqualify something if I strongly feel that it has above-average powerlevel.
Examples from official cards are, well, half of all cards ever published! There are plenty of great designs of weak-ish cards, like Oracle, Beggar, Shanty Town, Treasure Map, Rats, Windfall, Explorer, etc etc.
Qvist's Ratings are an optional but maybe useful resource.
Any card or Sideways is eligible, including split piles, knight/castle variants, cards with not-in-supply components, whatever.
As always, no mechanics from Allies or Plunder are permitted, but everything up to and including Menagerie is fair game.
