Become Gardevoir, they all want to capture me

"Hello, Professor Oak. Don't underestimate me because I'm a Gardevoir. I'm actually a human being, sealed in this body. My tens of millions of assets have been frozen. Now I only need a Pokémon Book and 6 Poké Balls to unlock them. Give me the things, and I'll give you 500 million in return..."
"Do I look like a fool to you..."
"Actually, this is what I am thinking, Professor Oak. I really am..."
"Even if you can talk, can you be a good elf?"
"……Can."
"Then can you help me predict what my grandson's future will be like?"
"Your grandson... Never mind, I'll just go and predict the stupid thing."
"..."
