This card's stats and effect make it the perfect card to use a Level 1 Tuner monster with to Synchro Summon "Enlightenment Paladin". Not only is this card a "Magician" Pendulum monster, which will allow Enlightenment its Spell-recycling effect, but this card will also give Enlightenment an anti-Dragon effect, which, while circumstantial, is a nice bonus. Additionally, "Tuning Magician" is the only Tuner monster that has direct synergy with Magicians and is not restricted like "Nobledragon Magician", and it is Level 1, so it is the best choice for this combination.
By using this monster as the Spellcaster fusion material for "Rune-Eyes Pendulum Dragon", and having "DNA Surgery", turning all monsters on the field to Dragon-Types, you can potentially pull off an OTK.
In a Buster Blader deck you can use this card to make your opponent's monster Dragon-Type and then easily run it over with "Buster Blader, the Dragon Destroyer Swordsman". This is very situational however and only useful if you don't have a "Buster Dragon" on the field. In some situations i.e. your opponent has 1 monster and no back row, it would be more efficient to use this Pendulum effect rather than to Summon "Buster Dragon". It's possible to OTK in a Pendulum Buster Blader deck combined with the "Hieratic" Dragons, as it is easy to swarm the field with "Buster Blader, the Dragon Destroyer Swordsman", "Crystal Wing Synchro Dragon" (through "Ultimaya Tzolkin"), "Buster Dragon", and "Gaia Dragon, the Thunder Charger" using a Rank 6 Xyz Monster ("Atum", "Beatrice", etc.) in one turn with the help of the "Hieratic" archetype.
As a Level 7 monster, it can be used as material for Red-Eyes Flare Metal Dragon. When used in conjunction with Red-Eyes Flare Metal Dragon's first effect, this combo can take down most Dragon-type monsters.
