You're terrible xD
But i have to agree with Elfy here. There's is a bunch of other pokes that could be better instead of the Pseudo-Legendaries.
Lust: I'll go with Ditto. It can breed with every single pokemon that can breed xD (Of course, i'm taking it to the "breeding side". It could be to others, if it was for money, food, etc.)
Gluttony: Snorlax no questions asked.
Greed: Persian. Just because of it's position in the original PMD
Wrath: Has to be Gyarados, duh. Goes on a rage, and destroys everything. And then, it does it again.
Envy: Gotta go with Eevee here too, because it's either eevee or ditto here for me.
Pride: Pfft. It has to be Giratina. I mean, c'mon
"It was banished for its violence. It silently gazed upon the old world from the Distortion World."
That's not really "prideful", but Giratina is basically Satan. And now, you can make the connection o/
