How do you combine a gravekeeper's deck and a dark magician deck?

You shouldn't them realy but I hope this helps. A gravekeeper deck example:

folish barial x3 g visionary x2 g cheif x1 and then g stele to pull them out x3

the part up there is optional

g comandant x2

g guard x2

g assailant x2

g spy x3

g decendant x3

misticall space tifun x2

allure of darkness x1

book of moon x1

double summon x2

waboks x2

metal reflect slime take this off if you want x2

trap hole x3 because botemless trap hole dosn't work cause of necrovalley

mirror force x1

dark illusion x2

necrovalley x3

total of 40 cards

I mainly run gravekeepers and it's a good deck to start with and remember that this deck main works because of necrovalley, g spy, and g descendant, I know that dosn't realy answer your question but realy you shouldn't mix gravekeepers.
