A good way to think about this card is that if you have used up all of your interactions already and your opponent still has another combo you should use this to destroy the monsters and hopefully stop them from doing anything impactful which should give you the ability to get total control of the game on your next turn
Cards like Vandalblast, By Force, Meltdown, and Bane of Progress can quickly clear away all your opponent's mana rocks, while land destruction cards like Wildfire, Destructive Force, cycled Decree of Annihilation, and Keldon Firebombers remove their lands
It gives you the choice of discarding one card, then allows you to draw until you have 6 cards in your hand
It feels modern and fresh, standing apart from traditional Zard artwork
The good news is that if Misty fails, you have a much more consistent chance of setting up before Dialga, giving you an easy lead
