As The Shadows Dance

[Illissius]

I've been submitting simple and elegant cards lately, so here's a more convoluted, top-down design. The name is the title of a song by Theatre of Tragedy, as it later turned out. (I had the phrase stuck in my head, and it appears that's where from.)

As The Shadows Dance

Enchantment
Whenever a creature attacks or blocks, its controller puts a black Shadow creature token into play with power and toughness equal to that creature's power and toughness, either attacking, or blocking a creature it can block of that player's choice. Remove all Shadows from the game at end of combat.

The idea was to design a card around the name. The shadows don't gain the creatures' abilities, because they're shadows, not clones. I toyed with the idea of giving of giving them Shadow (or only if the original creature doesn't have it), but eventually decided against it. I can't remember why, though.

No one has comments on this?

I think you might have to split the wordings up:

Whenever a creature attacks, its controller puts a black Shadow creature token into play tapped and attacking with power and toughness equal to that creature's power and toughness.
Whenever a creature blocks, its controller puts a black Shadow creature token into play with power and toughness equal to that creature's power and toughness, blocking a creature the blokcing creature could block.

The blocking wording is really hard to word properly. :/
