Mind Scan lets you see all the face-down cards on your opponent side of the field. You can learn what their plan is and be able to act accordingly when you see traps.
If you use Toon cards
You can get Mimicat, one of the best Toon supports, by leveling Pegasus up to 25. "It's a Toon World" skill, a random drop for Pegasus, is good if you use Toon deck. → Toon: deck recipe
About unlock event
Most of toon cards are only obtainable from the Pegasus unlock event. Once you finish the points mileage for the rewards in the event, you can still duel him to earn SR/UR tokens and drop skills. → Unlock event details

Creator Can be used if your Life Points drop below 2000. In the Draw Phase, instead of doing a normal draw, a powerful card, from outside of your Deck, is added to your hand. This skill can only be used once per Duel.
Extra, Extra Can be used if your Life Points decrease by 2000. During your Draw Phase, add to your hand 1 copy of the card you drew as your normal draw.
Maximillion Pegasus is the president of Industrial Illusions and the genius game designer who created Duel Monsters. He uses the power of his Millennium Eye to read his opponent's mind and see the cards in their hand. His Deck focuses on Toon Monsters to toy with his opponent. But when he gets serious, his "Relinquished" has an effect that enables it to absorb his opponent's monsters.
Use Counter Counter if Pegasus is using counter trap card to you. (Kartu counter perangkap paling kuat nih) tapi kalo lu aktifin kartu trap normal ke pegasus jadi bisa 4 kali chain, agak ribet sih tapi itu sekedar saran
...That isn't realistic. We're obviously not getting 3 copies of TToC, Rollback or TDMG, Millennium-Eyes Illusionist isn't happening, and I doubt Shadow Toon would either. (Also doubt they'd combine TER stuff and Toon stuff into one event.) There is other acceptable Toon stuff (AGG, Red-Eyes, Mask) anyway.
I've seriously got the worst luck.... Tryina get It's A Toon World
You do start with a copy of it, actually. Not sure if they changed his starter deck at some point or gamea was just wrong from the start, but looking at Wikia, he has Black Illusion Ritual instead of the third Eyearmor listed here. (The Card Catalog in-game lists it as part of his starter deck as well, so it's not just Wikia being mistaken.)
