Cults of Sewel: Mechanics

the Hero: (The hero is the creature that dealt the most damage to an opponent last turn, provided it also didn't deal the most damage to an opponent the turn before). Used on 0 cards:

Certain cards in the set will say "the hero can do this" or "your opponent's hero can't do that" or even "destroy the hero". This is referring to the creature who dealt the most damage to an opponent last turn. Creatures can't be the hero two turns in a row. If you did no damage to an opponent last turn or the hero did the most damage to an opponent last turn then you have no hero.

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}()]".
