I don't usually spend gold, but I got caught unprepared, and the A Time a Dozen event is based on these collections, so I thought it was worthwhile for Strength because of its types and for Astro and the reward for breeding Astro and Portal. Probably cost in the neighborhood of 150 gold, in total - for the tale and tournament. Ish. :-)
