Armor Lock

A card used by Serenity's boyfriend Michael in my Yu-gi-oh fanfiction "Checkmate"

All Michael's monsters are based on characters from the Halo 3 Machinima "Spriggs". They all have very powerful effects, the only downside is the ridiculous amount of cards they require you to discard in order to use them.

This trap card let's Michael protect his monsters from being destroyed in battle. But you still take battle damage, even if the damage is halved.
