I just dueled Pegasus and let me tell you that the list above is wrong. This is what I saw (the changes are on caps):
MONSTERS:
- 2 RELINQUISHED
- 3 BREAKER THE MAGICAL WARRIOR
- 2 Copycat
- 1 Djinn Disserere of Rituals
- 3 Toon Gemini Elf
SPELLS:
- 2 BLACK ILLUSION RITUAL
- 1 SORCEROUS SPELL WALL
- 2 Wonder Wands
TRAPS:
- 1 MAGIC DRAIN
- 1 Michizure
- 1 Skull Lair
He used almost every card on his deck. I don't know what is the card left on his hand. If you know what it is please reply to this comment. Thanks!
Nicholas is right, just checked his deck only 2 relinquished. I guess pegasus thinks 3 relinquished is too many. (I'm on ios if that makes a difference)
