Important Details about Passive abilities (although all members probably know these)
1) They cannot be lobotomized (Web vs Airborne is an exception)
2) Creatures can have any number of passive abilities
3) Passive Abilities must be Named
Great Idea for a thread EvaRia.
From my point of view, passive abilities rarely are the center of a card and thus do not make a good starting point for designing a specific card. However a list of well thought out passives with estimated Cost adjustments would be a valuable asset to card design.
I would suggest that we also split the list up between Buff, Neutral and Debuff types of passives.
Debuff
Infected X: Starts the game with X infection. Typically X would be 1.
Hungry X: Absorbs X random quanta per turn. Typically X would be 1.
Some select past ideas from here (

Recall: At the beginning of your turn, this creature returns to your hand.
Armor: Creatures with Armor have incoming damage reduced by X per source, just like a shield for a player. (Grav, Earth, Light)
Run Away: If this creature has 1hp at the end of your turn its returned to your hand.
Lucky Shot: Flip the coin if heads the attack is doubled if tails it misses
