What you think it is. Not opinions from others. I personally think that its not the power, but effect. Trust your heart, not people on the internet, and there s no such card as shadow lugia!
Arceus tin trust me I got an arceus lvl. X that does 1000 damage like shadow lugia
Try a pokemon heartgold tin like the meganium one
Trudi me its the garchomp tin
