[i]EARTH/Machine-Effect/Level 4
ATK/? DEF/0
When this card is Summoned, select 1 monster on the field. This card's ATK becomes equal to the selected monster's. If a monster you control attacks a monster with ATK higher than the ATK of your monster, you can negate the battle and inflict damage to your opponent equal to difference between the monster's ATK. You can activate this effect only once while this card is face-up on the field.[/i]

So you changed around the type/attribute/original ATK/level, then added a "your opponent cannot attack" clause to Copycat? I don't like the last clause, though, so eh =/

Wait, it was supposed to be other way around Changed
