I haven't been able to find any helpful videos on this. I've found videos that show how to script, but they use example cards that don't help with the specific card I'm trying to create.

The card that I'm trying to make can be special summoned from the hand by banishing one dark attribute monster on your field(Much like Red-Eyes Darkness Metal Dragon).

Its effect prevents the opponent from declaring an attack while it is on the field. (Much like Swords of Revealing Light, minus the initial flip effect and 3 turn countdown).

It'd be nice if someone also knew how to add archetypes into the game.(IE: Spellcaster, Dragon, Etc.)
And where is the Problem?
