As with Lands, I'll give a starting point: 8 - 10
It makes you some energy and can be used for limited mana fixing
It does require your opponent to have creature cards in their graveyard to get the full effect, but in formats like Commander, this will be rather common
There is no flavour text to the contrary, but since 'untapping' is essentially the game's shorthand for being unable to attack because they are doing something else (like activating their ability), I'm going to assume that Dance of the Dead causes the resurrected creature to dance the fandango unless you pay them money
You absolutely must test for your needs before relying on these to secure your decks since rounded edges, tapered sides and odd tops all have downsides
