Talk:Bone Master, Rebel Gallows/@comment-43897300-20200201043015

What is the exact meaning "if there are no cards in battle" ? If i have 3 size one monsters on the field including this Bone master rebel gallows, can my other 2 cards attack my opponent before I use the ability of rebel gallows ? Also, if my opponent has deity gargantua dragon and Aegir Gardra on the field, if I activate rebel gallows to control garga and attack my opponent, what will happen to aegir gardra ability "if your dragod attacks alone, it attacks your opponents and all their monsters instead", does it mean it attacks me and my monsters ? Thank you.
