Only "Destiny HERO" monsters can be used as Fusion Material for a Fusion Summon using this card's effect
[On Play] If your opponent has 6 or more cards in their hand, trash 2 cards from your opponent's hand
To put this in perspective, the next two cards on the list, Metalworker and Grim Monolith, account for 0.1% of the cards played in Legacy
The Vanquish Soul deck uses three of these since it can add other Vanquish Soul monsters to the hand
It uses the Jeskai color combination (Blue, Red, and White), and the included Commanders are Zinnia, Valleys Voice who serves as the main Offspring engine, and Arthur, Marigold Knight, who rewards you for attack with multiple creatures
No one really knows for sure what its sale prices were, and in fact no one even knows where the card is today
