Since this card has the second highest attack of any Tuner, next to "Life Stream Dragon", but is easier to put in your Graveyard, it works well with the card "Battle Tuned" to give a monster a major attack boost.
After Normal Summoning this card, you can Special Summon a "Turbo Booster" from your hand for an immediate Level 6 or Level 8 Synchro Monster.
By Normal Summoning this card with 1 monster and then using the effect of "Level Eater" on it, you can give yourself quick access to "Stygian Sergeants". By using "One for One" to Special Summon "Level Eater", you can accomplish this as quickly as your first turn.
Use "Advance Force" with this card to retain its level and original attack points.
Even better, use "Sinister Yorishiro" to Normal Summon this card with its original level and attack points.
You can use this card to synchro summon "Star Eater" by special summoning "Hieratic Dragon of Tefnuit" then Tribute Summoning this card. "Tefnuit" will be able to Summon a Level 6 Normal Dragon (like "Wattaildragon") to use with this card for the Synchro Summon of "Star Eater".
