KaibaMaster didn't specify the playstyle for this deck
Ive played every one of these cards in Commander, and while only some of them see consistent play in my decks today, all of them can bring more out of your mana base in a white Commander deck
Once per turn, when another card, or its effect, is activated (Quick Effect): You can negate the activation, and if you do, destroy that card, and if you destroyed a monster, this card gains ATK equal to that monster's original ATK until the end of this turn
Although her Pokmon TCG debut came in Black Collection [BW1], it was the reprint in Thunder Knuckle [BW8] that eventually became the definitive version for collectors
The effect of this card is risky to use, but when everything goes right you can reap a huge reward by doubling most mana across the board, you can use high mana maneuvers like those seen in a Vial Smasher not-white four-color commander deck
