Uh, this one I know we're gonna touch lightly, but I just wanna talk about, um, what is a dependency?
6:45
Dependency, yeah.
6:46
I, I actually d- briefly mentioned this slightly earlier, but, uh, a dependency is when one effect is, uh, dependent on another effect.
6:54
So, um, uh, as I mentioned, sometimes when you apply things in timestamp order, you get a, you would get an unintuitive result, and if two things are in the same layer, which we'll talk about what that means in a second, but if two things are in the same layer, sometimes one effect can change what another one does.
7:11
And the most obvious example of this is that if you have an effect...
7:15
Well, let's say you have a creature that says, uh, all your creatures have trample on it, and then you have another effect that removes abilities from the first creature.
7:25
Uh, if you were to apply those just strictly in the timestamp order, everything would get trample before this creature loses its ability, which doesn't make sense and is not intuitive.
