Sometimes sacrifices have to be made for a greater cause. There have been many such cases throughout history, and they tend to continue to this day.
When the first lands were sacrificed, many were left in shock. But in time, it became a usual practice once the benefits started to be recognized. Since then, citizens of Spellfire have started to make this kind of sacrifice more often.
The power of Sacrificial Lands can affect any razed realm in play. Its main purpose is to end the effect of an opponent's used psionic power. The player must sacrifice a card from his hand or discard a razed realm to end the effect, so difficult choices have to be made.
Once the card is sacrificed, the player is free to make further decisions for the safety of his kingdom.
