Since hearthstone added the new elusive keyword, I feel like The One-a amalgam band should have the elusive keyword too as part of the current keywords it can use
that is an interesting idea. although that then implies that adventurers from meeting stones should have an elusive version too, and toy soldiers from the toy chest, and so on.
he already has stealth which does what elusive does (except more)
edit: actually stealth can break after attacking so maybe they could consider that as a bonus of some sorts
