Labrynth is a slow as molasses control deck with the only restriction being that it can only access fiends after activating Welcome Labrynth. But, why not get more aggressive than "summon Ariane, set 5, pass". Enter Tour Guide From the Underworld.
Tour Guide can special Scarm from the deck and go through a Ghostrick line to summon U.F.D. In the process, Alucard will re-add Ghostrick Shot from the GY for free discard fodder. During the end phase, Scarm's trigger can search the level 3 fiend Labrynth Chandraglier who can immediately set a Welcome Labrynth from the deck.
The power of this variant is the additional Tour Guides in the deck which can also be searched via Scarm or stacked by Back Jack. These free bodies can easily convert to powerful fiend links: the Knightmares, Unchained Abomination, and Underworld Goddess of the Closed World. Resetting traps via Lovely Labrynth is just icing on the cake.
