A two-ink card, Bucky, Squirrel Squeak Tutor has the Ward keyword, meaning that it can only be targeted by being challenged, as well as its Squeak ability, which forces all other opponents to discard a card whenever you play a Floodborn character
He also would fit well with Steel, with their multiple ways to ping opposing characters
Cogsworth - Grandfather Clock helps keep your other characters alive to chip in occasional Lore, or more importantly keep them around to challenge more efficiently, keeping the Manor intact
Robin Hood - Champion of Sherwood (Into the Inklands) Robin Hood - Champion of Sherwood was a surprising find despite its downward trend in the past months
4 Arthur - King Victorious 221/204, Steel Arthur holding Excalibur aloft is a triumphant scene that's been depicted countless times throughout history, so taking it on even in the context of a card game isn't something to be taken lightly
Unlike character cards, however, they dont need to be exerted in order to be challenged as they are always exerted from the moment they are played and they dont ready (hence the horizontal way they are printed)
