It deserves a higher rarity (not that I'm complaining about it being a Rare) as it's pretty powerful and onoly requires a DIno Tuner as specific material. The card's text reads: "1 Dinosaur Tuner + 1+ non-Tuner monsters If this card battles, your opponent cannot activate Spell/Trap Cards until the end of the Damage Step. Your opponent's monsters cannot target monsters for attacks, except this one. Once per turn: You can target 1 monster your opponent controls; destroy it. If this card would be destroyed by battle or card effect, you can destroy 1 card you control instead."
