Rabiah Reborn: Mechanics

Wish: You may cast this card from outside the game by paying {3}

more as you cast it if you control a djinn. Used on 9 cards: Seal in the Lamp, Supernatural Intel, Cataclysmic Wish, Mystical Manipulation, Wish for Destruction, Wish for Insight, Wish for Unity, Wish for Downfall, Wish Out of Existence

Wishboards have often been a slang term for casting something from outside the game. Genies are known for casting wishes and now if you control one, they can provide this ability for you. Wish only appears on instants, sorceries, and enchantments.

Djinns, while obviously having elements of a traditional tribe, will be more spell focused than others.

Caravan: Used on 0 cards:

Caravan is a mechanic designed to provide a good payoff for going all in on your board. Different cards with caravan do different things if you control three or more creatures.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – {2} {r} {r} . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
