Pegasus' Creator skill is one of the skill to be updated during the upcoming rebalancing, changing the cards which you can get from the skill. A recent leak shows an updated list of cards you can draw with the skill.
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.
I've played hundreds of games with the Creator skill and it's gotten to the point that I can basically predict what card it will give me.
1. Dunames Dark Witch If I'm winning or don't really need a "powerful" card, it'll always give me Dunames Dark Witch.
2. Magical Arm Shield If my opponent has 1 powerful monster and another monster(in the hand or on the field), while all of my summonable monsters are lower in attack(in the hand or on the field), it'll always give me Magical Arm Shield. If they have 2 powerful monsters, it's always going to be Magical Arm Shield regardless of what you have in your hand.
3. Defender, the Magical Knight If my opponent has only 1 powerful monster(or none)(in the hand and/or on the field), and I have no comparable monster, it'll always give me Defender, the Magical Knight.
4. Breaker the Magical Warrior If my opponent has spells and traps on the field, as well as all monsters(in the hand and/or on the field) which can be killed with a 1600 attack Breaker, it'll almost always give me Breaker.
5. Harpies Feather Duster If I seemingly have no outs, no summonable monsters, or basically no way to win, it will give me Harpie's Feather Duster.
