Demerit

Demerit is a term given to the abilities that are detrimental to you.

Details
However, there are cases where they are not disadvantageous to you, or can be changed to be an advantage.

Creatures with these demerits are often creatures that have blocker, but have a higher cost to power ration than other cards.

This card has a Come Into Play ability that is a demerit of returning a card from your mana zone to your hand. However, it can be treated as an advantage by returning cards that have been put into your mana zone by Mana Acceleration, or high cost cards put in the earlier turns before they could be played.

Examples of Demerit abilities

 * "Can't attack"
 * "Attacks if able"
 * When you put this creature into the battle zone, destroy one of your creatures.
 * Reverse Slayer (When this creature loses a battle, destroy the other creature.)
