You can also use skills like Destiny Draw to get a specific card from your deck.
Some Field Spells have cards that can search them, e.g. Zeradias, Herald of Heaven.
Duel Links doesn't have the good generic searchers like Terraforming or Metaverse. But you can use Ancient Fairy Dragon, Planet Pathfinder or Owl of Luck. Other cards like Pop-Up or Demise of the Land can work too but they are more specific.
