Wrath of the Reptilianne

Stall until you get into a favorable position to summon strong monsters. Destroy Sangan and Reptilianne Gardna to search for most monsters in the deck. Reptilianne Gardna in particular searches for Reptilianne Vaskii, a boss monster whose effect can destroy a face-up monster your opponent controls every turn. To summon Vaskii, you can tribute the tokens generated Dandylion. 

Edit: Updated with a Lonefire Blossom engine. Lonefire Blossom can search for Dandylion, who generates tokens more consistently than Scapegoat and Fires of Doomsday.

On the Embodiment of Apophis

The Embodiment of Apophis is a continuous trap that special summons itself as a reptile monster. It's a flexible effect that can provide fodder for Magic Planter and Offerings to the Doomed.
