OK, so I was looking through my Platinum cards when I came across this awesome card. I've not actually seen it used before, and I can't see why. Time Aura is a great lock to stop the opponent from evolving and buy time whilst you prepare for a Metal Burn.
The thing is, after a Metal Burn, you need to discard all Steel Energies attached to Dialga. I was trying to think of a way to overcome that and I'm sure there's a way. If you attached 2 Rainbow Energies to him, would you have to discard them if you were using them as Steel Energies? If not, are there any other ways to keep Metal Burning without penalties? If this card was played right, it could be a dangerous weapon.
Let me know what you think about this card!
I am also aware that there may be an old thread about this, but I couldn't find it, so my apologies if this is a repeat.
