Blocker is an evergreen keyword shared between the Light, Water, and Darkness civilizations.

Details

Whenever one of your opponent's creatures attacks you or one of your other creatures than the blocker itself, you are able to tap one of your creatures that has the "Blocker" ability to be attacked instead, blocking the attack. The two creatures then battle each other.

Note that being a blocker is not always a good thing to creatures as sometimes it makes them easier to destroy and become susceptible to Blocker-based removal cards.

"Diamond State" cards can allow creatures that have Blocker and/or cannot attack players or attack at all to attack.

Each civilization features key differences with its creatures that have a blocker ability. These include;

Light — Has the most amount of creatures with the ability. Their lower powered creatures often can't attack players.
Water — Their creatures often can't attack at all and those who are able to attack feature low power.
Darkness — While creatures that have the blocker ability are less numerous, they often have the Slayer ability as well. Some also have higher than usual power but are destroyed when they win a battle. A few are able to still attack but feature low power.
Nature — Only exists with Supernova Bigbang Anastasis and Ebard Zenom, Tree Pulse Guardian.
Colorless — Wide variance of abilities. Each are able to attack.

This ability has a weaker variant on Fire and Nature creatures, Guardman.
