Text (UG+errata): {4},{Tap}, Sacrifice ~this~: Put into play from your hand any card from an Unglued supplement. [Oracle 2009/07/08]
As always, X is zero if this card's ability is used. Y and Z can be any numbers you choose. [Barclay 1998/08/13]
Optional Rule: If used to put a Chicken Egg into play, that egg is immediately "cracked" to create a Giant Chicken. [Barclay 1998/08/13]
Optional Rule: This cannot put Sorcery or Instant cards into play. However, it does allow you to play those spells, paying "{4},{Tap},Sacrifice ~this~:" instead of the regular mana cost. [Barclay 1998/08/13]
All tournament formats have banned cards from Unglued.
