Depends...
Note that there are *two* Blairs and two Tolwyns. The Tolwyn you see below is the promo that might have come with WCIV... there's also a regular Tolwyn card that came with the game.
(Ditto for Blair -- there's a promo and a regular card).
The Blair and Tolwyn cards with the game were both classed as 'rare' -- which, for WC, meant that there were two in each pack.
The promos were not available in packs -- the Blair was given away at GenCon in 1995, the Tolwyn with WCIV. Generally, the Tolwyn is much rarer than the Blair.
