Is this a good card trade(yu-gi-oh)?

I'm getting Inferno,tempest, 5 different barrier statues, and about three more cards that i could use with my deck for my Dark Eradicator Warlock. First of all I don't have a dark magician and he does, but I want to get one without paying fortunes, besides since we play against each other I don't want to be used against a card I use to own (even though I can't use it, but want to keep it), but there is a good side, I might be giving a good card for a lot of cards I can't really depend on but I can use Inferno tempest with my golden homunculus. Tell me is this a good deal for one warlock for 8 cards I can't even depend on and one great card? If not what would be a good trade for my warlock, just use different cards you think would be a great trade in comparison to his.
