Superhero: Mechanics

Endless: At the beginning of each upkeep, if this card is in your graveyard, put it onto the battlefield. If this card would be exiled, instead return it to its owner's hand. Used on 7 cards: Despair, Destruction, Delirium, Dream, Destiny, Death, Desire

This is to showcase how the Endless themselves are concepts and can't be killed, even if the creature is killed.

Suspend: Rather than cast this spell from your hand, you may pay PARAM2 and exile it with PARAM1 time counters on it. Used on 1 cards: Ozymandias

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}()]".
