/**
* 10/4/2004   The mana cost of the creatures being cast is still the stated cost on the card,
*              even though you did not pay the cost.
* 10/4/2004   Aluren checks the actual printed cost on the creature card, and is not affected
*              by things which allow you to cast the spell for less.
* 10/4/2004   You can't choose to cast a creature as though it had flash via Aluren and still pay the mana cost.
*              You either cast the creature normally, or via Aluren without paying the mana cost.
* 10/4/2004   You can't use Aluren when casting a creature using another alternate means,
*              such as the Morph ability.
*  8/1/2008   If creature with X in its cost is cast this way, X can only be 0.
