Master of Rites Can be used each time your Life Points decrease by 1000. This Skill can only be used twice per Duel. Return 1 card from your hand to your Deck and choose 1 of the following: • Add random Ritual Monster to your hand from your deck. • Add random Ritual Spell Card to your hand from your deck.
Not at all. The Sonic Bird and Senju of the Thousand Hands are both URs from very old packs. Ultimate Rising and Neo-Impact specifically, which means you'll be dropping A LOT of gems on those cards and most of the cards you'll be getting are pretty worthless these days.
I was Konami would re-release them both In a newer pack. They're both so integral to Ritual decks.
