Honestly, to use Ty Prime well, you almost never use his last attack. Darkness Howl is his best attack, and his second attack is good for a lot of situations, like Umbreon UD, the opponent having Special Metals, etc. But, if you use his last attack, you set yourself up to be decked. I mean, you can run multiple Palmer's/Flower Shop Lady, but you'll still be losing valuable trainers.
