SR12-JPP01 Master Flare Hyperion
Q: I control a Celestial Knightlord Parshath and a Master Flare Hyperion that has gained the name and effects of Celestial Knightlord Parshath. In this case, can both cards activate the effect of Celestial Knightlord Parshath that adds The Sanctuary in the Sky or a card that specifically lists “The Sanctuary in the Sky” in its text from the Deck to the hand, during the same turn?
A: Between Celestial Knightlord Parshath and a Master Flare Hyperion that has gained the name and effects of Celestial Knightlord Parshath, only 1 of those cards can activate the first effect written in the text of Celestial Knightlord Parshath.

Q: If Master Flare Hyperion has gained the name and effects of Celestial Knightlord Parshath, can that Master Flare Hyperion activate the second effect of Celestial Knightlord Parshath (the “②” effect written in the text of Celestial Knightlord Parshath) and its own second effect (the “②” effect written in the text of Master Flare Hyperion) during the same turn?
A: They can be activated during the same turn.

SR12-JP001 Majesty Hyperion
Q: The effects of The Sanctuary in the Sky and the effect of my Majesty Hyperion are applying. In this situation, what happens if my Attack Position Majesty Hyperion (Fairy/ATK 2100) battles my opponent's Attack Position monster with 3000 ATK?
A: In this scenario, the effect of Majesty Hyperion makes it so that your opponent would take 900 damage, and the effect of The Sanctuary in the Sky makes it so that a player does not take any battle damage from a battle involving their Fairy monster. Therefore, if your opponent's monster is a Fairy monster, neither player takes any battle damage. If your opponent's monster is not a Fairy monster, only your opponent takes 900 damage. In either case, Majesty Hyperion is destroyed by battle.

Q: Each player controls a Majesty Hyperion, and their effects that make the other player also take any battle damage their controller takes from battles involving their Fairy monsters are applying. In this situation, what happens if my Attack Position Majesty Hyperion (Fairy/ATK 2100) battles my opponent's Attack Position Master Hyperion (Fairy/ATK 2700)?
A: In this scenario, only the effect of your Majesty Hyperion is applied, so each player takes 600 damage. When your opponent also takes battle damage due to the effect of your Majesty Hyperion, the effect of your opponent's Majesty Hyperion will not be applied to that battle damage.
