Temur Lessons is a value-grinding deck built around Lesson cards like Firebending Lesson and Accumulate Wisdom plus the mana-sink threat Thor, God of Thunder, so taking away their best card before it compounds is strong. Duress and Cruelclaw's Heist both proactively strip key pieces like Tablet of Discovery from hand, with Cruelclaw's Heist also able to grab Thor and let you cast whatever you take. Get Lost is unconditional removal for Thor, God of Thunder or Questing Druid once they resolve. Requiting Hex struggles to find legal targets since their real threats are mostly above mana value 2, so it comes out along with Emptiness and a mainboard Voice of Victory for more proactive answers.
