Relinquished
DARK/Spellcaster/Ritual/Effect/Level 1/0/0
You can Ritual Summon this card with "Black Illusion Ritual". Once per turn: You can target 1 monster your opponent controls; equip that target to this card. (You can only equip 1 monster at a time to this card with this effect.) This card's ATK and DEF become equal to that equipped monster's. If this card would be destroyed by battle, destroy that equipped monster instead. While equipped with that monster, any battle damage you take from battles involving this card inflicts equal effect damage to your opponent.

Finally this week is Relinquished, one of my favourite cards of all time and it hasn’t been reviewed since its release.

Statwise Relinquished isn’t much, it is a DARK/Spellcaster so there is plenty of support there, with 0 ATK and DEF which is bad no matter what the level of the monster. Of course Relinquished is a Ritual Monster which is sadly under-supported but Relinquished is level 1 so getting him out is very easy.
 
Of course Relinquished’s main thing is his great effect, he can target 1 of your opponent’s monsters and that monster equips to Relinquished, turning that monster’s ATK and DEF against its owner. Plus while it has a monster equipped, the opponent takes any battle damage involving Relinquished making them carefully when attacking Relinquished, especially when the equipped monster is destroyed instead of Relinquished..
 
Despite being one of my Favourite cards, Relinquished isn’t perfect. It is a ritual monster so all the problems that they have apply to him. Also if he loses his equipped monster due to battle or generally a card effect or his effect is negated then you are stuck with a monster with 0 ATK that is probably in ATK mode.

Overall a fun card and it can be quite dangerous but being under supported as a ritual; it probably needs its own deck.
