[BOSH] Odd-Eyes Advent

This card can be used to Ritual Summon any Dragon-Type Ritual Monster from your hand or Graveyard. You must also Tribute Pendulum Monsters from your hand or field, and/or if your opponent controls 2 or more monsters and you control no monsters, send "Odd-Eyes" monsters from your Extra Deck to the Graveyard, whose total Levels equal the Level of that Ritual Monster or more. You can only activate 1 "Odd-Eyes Advent" per turn.
