If you use high-Level monsters in your Deck to Special Summon by this card's effect, you can avoid dependence on your opponent's monsters' Levels by using high-Level "Ninja" monsters to use with this card that are easy to Summon, such as "Earth Armor Ninja" and "Twilight Ninja Getsuga, the Shogun".
Although "Flame Armor Ninja" is a Level 4 monster, it can use its effect on itself to boost its Level.
If you Summon "Galaxy-Eyes Photon Dragon" by this card's effect, try to use its effect as soon as possible in order for it to be unaffected by this card.
"Tyrant Dragon" is an interesting monster to Special Summon with this card, since it can attack twice during each Battle Phase, and its own effect will negate and destroy this card (once Summoned) without being affected.
Keep in mind the dangers of using too many high-Level monsters for this card to Summon, as they can accumulate in hand before you get to use this card, or the dangers of using too many copies of this card in the Deck.
