send Darkest Diabolos to the GY to easily special summon it
use Ahrima to search importants cards like Lair of Darkness or Darkest Diabolos and use Tour Guide to search Lilith
use Lilith and Lair of Darkness to get rid of opponent's monsters by tributing them (work even if the effect of Lilith is negated because the tribute is a cost)
keep Lair of Darkness on the field to tribute opponents monsters and avoid annoing monster's effects when destroyed by cards effect.
very trap heavy but searchable with Lilith and Malice.
(still work in progress; some side-deck cards are there to counter friends' decks :-) )
