Hero Shall Cast Its Light

At the beginning of the Duel, add Pendulum Zones to your field. If you control "Timebreaker Magician", the following effects can be used once per Duel. - Add 1 "Tuning Magician" from your Deck to your Hand. - Change the Level of 1 Level 3 or lower Spellcaster-Type monster you control to 4. During the turn you use this effect, you cannot use that monster as a material for Xyz Summoning a monster, and Spellcaster-Type Synchro Monsters you control gain 500 ATK. This Skill can only be used/applied if you begin the Duel with an Extra Deck that contains at least 3 Synchro Monsters, including "Enlightenment Paladin".
