I think decoy dragon is a nuts card in the right deck. In a way he functions like a spirit reaper. Although he can be destroyed by battle, having high level dragons in the grave makes him impervious. Plus if I'm reading his text right he stays on the field after using his effect, so as long as you have lv 7 + dragons in the grave he is impervious to battle.

Of course, I will assume his effect does not work if he is face down, and noone is going to attack your decoy dragon when blue eyes is sitting in the grave.

SO my question is how can we make them attack and how can we fill the grave up with high level dragons?

The title of the thread is a start. You have decoy + 1 other monster, they attack the other monster, you flip staunch defender and get a high level dragon for every monster they have. Mirror force + X monster reborns in one combo, not too bad.

Are there any other cards that make opponents attack? Also how can we fill the grave? Of course future fusion for five head is a dragon staple, and foolish burial is a great help as well. And since we are prob going to be using lv 8 dragons we can throw in some trade ins as well.

What do you think is decoy dragon worth building a deck around?

Staunch Defender + Mirror Wall + lvl 7 monster.
