Just a note of a tricky rules wording on the card
Deicide:
Exile target enchantment. If the exiled card is a God card, search its controller's graveyard, hand, and library for any number of cards with the same name as that card and exile them, then that player shuffles his or her library.
Unlike most of cards of this kind (like
Splinter),
Deicide checks the card's stats AFTER exiling it, not before. This means some of the behaviours are different:
1. If the permanent is not a God, but the card after exiling is,
Deicide will get rid of copies (for example, if the God doesn't have enough devotion to be a creature -- this is most likely the reason for the wording). If the card is a God, but NOT an enchantment after exiling (for example a changeling when
Enchanted Evening is on the battlefield),
Deicide will work regardless.
2. If the permanent is a God on the battlefield, but not in exile,
Deicide won't get rid of the copies. Example could be a
Clone or
Copy Enchantment copying a God.
3. If there is no exiled card,
Deicide won't get rid of the copies. Example could be targeting a token copy of God.
4. If you target a God that is changed into a copy of something else (like Erebos changed into Heliod by
Polymorphous Rush),
Deicide will exile copies of Erebos, not Heliod.
Also allow me to use this space to point out a minor bug with "search and destroy" cards like this. Some cards, like
Deicide and
Memoricide, use wording "for any number of cards with that name", allowing you to not exile all cards. Some other, like
Cranial Extraction, use "for all cards with that name and exile them" and Forge automatically exiles them all.
The problem is that these two wordings actually differ ONLY for searching the graveyard, but when searching hand or library, the player should always have the option to leave some cards, even with "all" wording. That's because hand and library are hidden zones and when searching in hidden zones for a specific kind of card, you're automatically allowed to not find it.
Cards affected should be:
Counterbore,
Cranial Extraction,
Eradicate,
Extirpate,
Haunting Echoes,
Lobotomy,
Quash,
Scour,
Shimian Specter,
Sowing Salt,
Splinter and
Thought Hemorrhage.
