DP: Oh, no
Melek, Reforged Researcher I think the last part of this card to be balanced in design was the mana value because getting this much cost reduction on your first spell each turn is ridiculous, and if you could cast Melek, Reforged Researcher any earlier, it'd be broken
When your creature can be recycled this often, you're getting a lot of value out of two mana
You can morph it for three and then unmorph for five so it might be good enough but I found it intriguing enough to consider
As this deck was going big anyway, I decided to add in some really expensive stuff, like Desolation Twin, the Kozileks, and an Ulamog
Miserys Shadow Denying death triggers can be a powerful tool and if youre someone who already plays Dauthi Voidwalker, Leyline of the Void or Valentin, Dean of the Vein then make sure to pick up a Miserys Shadow
