I keep hearing these comparisons between Pelacor Mercenary and Flesh Golem, There is one important distinction: it doesn't get it's heal until level 6 so doesn't work in bronze or silver league as Flesh Golem.
Similarly with Pelacor Conjurer. He doesn't get magic reflect until Level 4, so not available in bronze. Failed Summoner gets it at level 1 so very inexpensively.
Yes, that's true and I noticed that as well. I guess, they have to differentiate those cards in one shape or form otherwise, they'll just be copy cat. At low level, it matters but maybe at Gold level, it does not.
