Turn 2: Kaiba

Kaiba draws. He then Normal Summons "Spear Dragon" (1900/0) in Attack Position. "Spear Dragon" attacks and destroys Leichter's face-down monster. It's revealed to be "Hiro's Shadow Scout" (650/500). "Spear Dragon" then inflicts piercing damage to Leichter (Leichter 4000 → 2600). Since "Hiro's Shadow Scout" was flipped, its Flip Effect activates, forcing Kaiba to draw three cards and reveal them and if Kaiba draws any Magic Cards through this effect, they will be discarded. The revealed cards are "Cave Dragon", "Double Snare" and "Magic Reflector", and the latter two cards are discarded. "Spear Dragon" switches itself to Defense Position at the end of the Damage Step due to its second effect. Kaiba Sets a card ("Crush Card"). On Kaiba's End Phase, Leichter activates his face-down "Solemn Wishes". Now each time Leichter draws a card, he will gain 500 Life Points.

"Spear Dragon" attacks Leichter's face-down monster, but Leichter activates his face-down "Mask of Perplexity" to redirect the attack to "Giant Germ", destroying it (Kaiba 4000 → 3100). Kaiba attempts to activate his face-down "Crush Card" which will destroy every monster in Leichter's hand, field, and Deck with at least 1500 ATK, but Leichter activates the Deck Master ability of his Deck Master: by firing a bean from his eyes that negates all of Kaiba's Trap Cards. Kaiba then figures out what Monster Leichter has chosen for his Deck Master. Leichter removes his clothing and reveals he is "Jinzo".

Leichter takes abreak from the duel to remind Kaiba of one of his past birthdays. In it Gozaboro offers Kaiba 10 million dollars as a test of his business skills. The task: He is to make ten times the amount he was given within a years time, and Gozaboro offers the assistance of Leichter as the only help he will get.

Kaiba manages to come up with a plan: In order to control a company he needs a large amount of stock to buy it out. The number is 51. If Kaiba can control 51% of a company, he can control it all. he instructs Leichter to invest 51% of his given money, $5,100,000, into any company, on the condition the company in question values it's workers. Leichter manages to find a company that treats its employees like family, but might not make enough, unless Kaiba runs the company his way. He strongarms the owner and buys his company, and at the end of the year, Kaiba did make the amount Gozaboro set up for him.
