After looking at your opponent’s set cards you can then appropriately use removal for problem cards. Use cards like Nobleman of Crossout or Nobleman of Extermination to deal with set cards. Use Anti-Magic Arrows or Hey,Trunade! to deal with battle phase Traps.
Discarding Thunder Dragon is a good way of loading your graveyard with cost for special summoning Lucius while also thinning your deck.
Some monsters can destroy your opponent’s cards upon summoning. Use Lucius to tribute summon into them to know what you are destroying. Or to know what kind of monster you are attacking into and what backrow your opponent has in place.
