Evoke: You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters the battlefield Used on 4 cards: "Shrivel", Ender of Days, Experimentation Chamber, Inspiring Angel

Evoke is a keyword ability that allows a player to play an alternate cost for a creature spell that possesses this ability; however, if the evoke cost is paid, the creature is sacrificed when it comes into play. Evoke was introduced in Lorwyn.

Righteous: Used on 0 cards:

This is an ability word which will only be on white creatures. It will react if an opponent controls a red, green or black permanent. For example, "Righteous - when this ETBs, if an opponent controls a red, green or black permanent, draw a card."

Might not need to be an ability word, maybe a nameless mechanic.

Probably going to be left out in favour of Rally

Augment: As you cast a creature spell, you may reveal this card from your hand and pay its augment cost. If you do, add this card's effects to that spell. Used on 2 cards: @@@Bloody Augmenter, @@@Cheap Augmenter

An ability that could conceivably be on Enchantments (not Auras), Artifacts, and other Creatures.

*Rally* - If you control 3 or more \1, other : Used on 2 cards: RW01, Rousing Watchman

This is an ability word mechanic similar to Metalcraft which gives bonuses for assembling an army. This is a white mechanic in this set.

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}()]".
