UchihaBlood said:Ok think of it this way.
When you attach a Holon's Castform to Mag,you must pick up an energy so if you really think about it you are taking off 20 damage for his first attack.Plus you have to ask yourself,what happens if I start with Holon's Castform in a deck with no {d} Pokemon and how will you recover? Plus you would still only remove 2 damage counters,because Magmortar clearly states that when you attach a (F) Energy from your hand to Magmortar remove 2 damage counters.
Hope I helped!
