Change of Heart Monster

"Change of Heart Monster" (心（こころ）変（が）わりなモンスター, Kokorogawari Monsutā) is a Duel Puzzle in Yu-Gi-Oh! Duel Monsters 5: Expert 1.

Setup

The player begins with 1200 Life Points. Their hand contains "Terra the Terrible", "Judge Man", "Blue-Eyes White Dragon", "Change of Heart", "Key Mace" and "Skull Servant". Their field contains "Giga-Tech Wolf" and "Fireyarou", both in Attack Position.

The opponent has 2000 Life Points and their field contains "Harpie Lady" in Attack Position and "One-Eyed Shield Dragon" and "Hard Armor" both in Defense Position.

The player is given the hint: "Judge Man" and "Blue-Eyes White Dragon" are the cards to win the Duel. But just Summoning them won't change the situation, so you must use your Spell Cards the right way.

Solution

1. Activate "Change of Heart" to take control of "One-Eyed Shield Dragon".
2. Tribute "One-Eyed Shield Dragon" to Summon "Judge Man".
3. Enter the Battle Phase.
4. Attack "Hard Armor" with "Fireyarou".
5. Attack "Harpie Lady" with "Judge Man".
6. Attack directly with "Giga-Tech Wolf".
