Realms cannot be affected by spells or abilities controlled by an opponent. Players cannot draw cards from
an opponent's realm.
Whenever a player draws a card, that player can draw from any colored library they like. Or, the player
may draw from his or her realm library.
Decks can sometimes grow to thousands of cards. During a game I use 50-70 cards for each color to use during
that game. Any tutors are limited to searching a single colored deck, not the 1000's stored in the big box.
Players can look at each card as they draw their opening hands.
Players keep their own separate graveyards.
The player that draws a card is considered that card's "owner".
Returning Cards to Libraries
Whenever a card is returned to a library, it returns to the library it came from. For instance, Time Ebb returns
green creature cards to top of the green library .
Choosing a library to draw from does not use the stack, so no one can respond to it. For instance, you can’t
Reclaim a crap card onto a library after a player has decided which one they will draw from.
Who Picks which Library
The controller of the spell or ability chooses the library it affects.
Revealing the Top Card of Libraries
If a card continuously reveals the top card of a library (such as Wizened Snitches), its controller chooses
which library that card affects when the card enters the battlefield.
Whenever a player searches a library, that player may only search one library. This includes scrying and effects
that allow a player to look at the top cards of a library, like Ponder.
Multiple Players Searching a Single Library
If two or more players would simultaneously search the same library, the controller of the spell or abilty
searches the library first. Subsequent players search in turn order.
Check the researcher page for this mechanic. When players are drawing from huge decks, a bit of looting can
give them more control over their fate. The researcher is a planeswalker that starts the game on the battlefield, giving players
a limited ability to loot.
Artifacts and non-basic lands are allowed in decks. If a colorless card has a colored mana symbol in its rule
text, it is recommended that the card be included in the deck of that color.
Gold and Hybrid Cards
Hybrid cards are allowed in decks. However, gold cards are often difficult to cast in this format and are
not recommended. The exception to this is the "easy cast" gold cards like Slave of Bolas.
See the "Ideas" page for more details on gold, hybrid and colorless cards.
