Forum:Relinquished card effect

What type of effect is Relinquished considered as? The wikia says it's considered an Ignition, Continuous, and Trigger, but I don't know which effect is which.

"Once per turn, select 1 monster your opponent controls and equip it to this card (only 1 monster can be equipped to it at a time). This card's ATK and DEF become equal to the ATK and DEF of the monster equipped to this card. If this card is destroyed by battle, the equipped monster is destroyed instead, and any battle damage you received from the battle is also inflicted to your opponent." -Relinquished's tool tip from wikia

The first sentence, "Once per turn, select 1 monster your opponent controls and equip it to this card." does not look like a ignition effect to me because it doesn't seem like it's optional to equip a monster your opponent controls.

"Ignition Monster Effects require a manual activation by the card's controller during the Main Phase 1 or 2 of either turn" -yugioh wikia

So can someone please clarify to me the Ignition, Continuous, and Trigger of Relinquished's Effect? -Thanks
