A/N: As requested by Infiny, a short poem on the Change of Heart card!

Duel Monster enemy of mine, hear my cry,
Do you know where your loyalties really lie?
Who do you heed? Who is your sire? Under who do you cower?
I've made that even more unclear, that is my mysterious power.

I can force you to obey another, turn against your friends.
When that happens, who knows how the duel ends?
Monster under my watch, you don't know where to end or start.
But it looks to me as if you've had a . . . change of heart!

Obey instead my master, listen to his orders, his commands.
I've brought over to this side, just by a touch of my hands.
Confused? There is no way you can resist my power, my might.
I can force even a mage of the Light to turn towards the night.

Come to us, minion of the enemy.
Your heart is no longer so free.
