* Add concise game-oriented info to each PW page. E.g. how good the PW is; basic strategy guide for Loyalty abilities (which abilities to use when); what style of deck works best (control/aggro/...); whether the PW is required for specific events; any known bugs; etc (any other pertinent PW-specific info useful to players).

* Add a page describing [[Deck slot]]s
