My question here is about the interesting wording--"enchantment artifact". Looking at Celestial Archon--which can be cast as an aura on another creature rather than a creature itself--makes me wonder if this wording is going to tie into something more. Might there be another spell that allows enchantment permanents to be used another way? Or is this just an added weakness in that enchantment destruction/prevention would be a foil? I'm no rules guru by any means, but the word "enchantment" being attributed to all of these other permanent types tells me that there's something afoot.I thinkThe flavor on those black cards is just crazy good. I love Read the Bones for both scry and draw.
Not sure about the Hammer of Purphoros

Creatures you control have haste.
2R, Tap, Sacrifice a land: Put a 3/3 colorless Golem enchantment artifact creature token onto the battlefield.
That seems rather unexciting. With all the other effects that grant haste already, this was what they thought of? Granted, it does help for when a red deck gets land flooded. I would rather it had a slightly higher activation that allowed you to destroy any land.
it is pretty good. Remember that it hastes the golem token, so you're generating a 3/3 haste every turn your draw a land if you like.

I just took a gamble...$36 for a playset of Cerberus. I fear things may be such that it ends up around $5, but the fact that prices on it
on ebay are all over the map makes it seem a worthwhile gamble. If a few more enabling cards spoil, it will shoot up for at least a bit; if not, ah well...the flavor of these cards alone makes me want to have a set to put away.
I actually got chills when I noticed how masterfully they wove these abilities into the flavor of the mythos. Cerberus guards the gates of Hades, and thus none of the dead can escape while he's on the board--no Rescue from the Underworld, no reanimation, zip. When he leaves the battlefield, the gates go unguarded and all the souls in Hades escape and can be therefore returned to life on the battlefield. That to me is next-level design...so immersive!!
