Gardevoir ex this, Miraidon ex that, who needs them when you have Toxicroak ex

I was opening some ScarVi packs when I came across the absolute unit that is Toxicoak ex. At first glance it isn't a very strong card, dealing 120 damage per hit plus 6 poison damage per turn for 1 Darkness and 2 Colorless Energy. However, I have found a way to make it work. Here's the decklist:

The idea is to get Tox and HSamurott out ASAP, to drop Moon Cleave Star, get RAlakazam to spread the damage out for HSamurott to hit hard, and use Tox to supplement extra damage counters for Alakzam. The best part of this deck is the potential to obliterate Gardevoir ex, which is a very popular deck at the moment. Use this know wisely.
