Swarm the Field with Harpies, interrupt your opponent with Harpyies Feather Storm or extra-deck monsters like Abyss Dweller and Bagooska.
Tempest and Dogman let you go easily into Dracossack, the BLS Link or Big eye for crushing cards or steal a Monster and control the field.
The Dangers themselfe are extenders for Rank 4 and 7 plays, let you dig deeper into your Deck. Also Dogman can compensate the lack of ATK (one main Problem of the Maindeck-Monsters).
If the Board is cleared, you can overlay for Lightning, causing 5000 Damage (often OTK if you have 2 more Harpies or another extra-deck monster on the field).
If your opponent has a full board and a weak Monster in ATK: clear the backrow with Hunting Ground or Dracossack, drop a Feather Storm and overlay for Utopia Double, attacking for Game (Double-->adds Double or Nothing from Deck-->Overlay normal Utopia-->Attack/Negate with the effect of Utopia, then drop Double or Nothing --> GG)
