I'm not sure what you guys think but IMO meditite DR can be very useful against ampharos ex. As long as ampharos ex has at least 50 damage on it, use meditite's meditate, which does 10 damage plus 10 more for each damage counter on the defending pokemon. This means when ampharos has 50 damage on it, meditite will do (10+50)x2 =120 to ampharos ex, together with the 50 damage from before, ampharos ex would be knocked out. You can keep meditite in your hand until your opponent's amphy has at least 50, then just play it, attach an energy, use energy switch and look at your opponent's face when his/her ampharos ex falls. You can also do this to other high hp pokemon with enough damage counters on them to be koed by meditite in one hit. I put meditite in my kingdra ex deck to counter amphy (the link on my signature below), what do you guys think?
