Card Rulings:Solidarity

OCG Rulings

 * The effect of "Unity of Family" increases the ATK of a monster if the monster's current Type is the same as the Types of all monsters in your Graveyard. If you only have Warrior-Type monsters in your Graveyard and you control "DNA Surgery" declaring "Warrior" and a Dragon-Type monster, then the Dragon-Type monster will gain 800 ATK.
