Yoshidude10, You're pretty close. First, you should probably specify the 9th card is the draw for the turn. Also, it's not so much the T2 Typhlosion as it is the Rare Candy and Typhlosion in the same hand. Those 9 cards plus however many were in your hand already gives you a great chance of getting that when you need it. Finally, it comes at a HUGE sacrifice - 3 cards and an energy. It's just the consistency that makes it good.
But you're on the right track. Nice job!
