Pros of the card:
Gets rid of the opponent's Shard of Gratitude,
Deals 5 Damage
Cons of the card:
1. Hardly any SoGs outside of a few FGs and T50, and won't be used otherwise...
2. 5 Damage is hardly any damage for such a card.
3. There's other cards out there that would be easier to use, such as Deflagration that can destroy the SoG or OTHER PERMANENTS.
This card was a good idea, but it would be stupid if it was implemented like this.
