Bringing just the 2 normal fusion material monster with King of the Swamp, you can use them in a gemini deck for some synergy. Equip Supervise on Blazewing Butterfly, or any other Gemini monster, and send activate Tempest's ability to send it to the graveyard. This will allow you to special summon either your destroyed normal monster material, or any other strong gemini monster, while also selecting Blazewing through Tempest's effect to make sure it won't get destroyed by battle.
If your opponent summons a monster that has higher attack than tempest, you can use Magical Reflect Slime, or Amazoness Swords Woman to keep dealing damage by attacking into them. You only need to protect your Tempest from getting destroyed. Use cards like Enemy Controller, or Windstorm of Etaqua for that.
