Overall a great card, the downside is it won't help any EX pokemon, and that's where this card's downside is: It can't heal EX pokemon who are most important in battle if you have them up. Anyways, it can steal do well in healing a stage 2 of 3 pokemon, but you need to flip heads first. Kabutops from Holon Phantoms has with Vital Drain a similar effect, and personally I like that better since it's effect is about the same of Life Herb and you don't need to flip a coin.
