During a battle, I use Top Drop against my friend's Darkrai LV.X. Darkrai LV.X has a weakness to {F} Pokemon, by x2. I Top Drop a Bronzong MD, which has 90 HP. My friend claims the attack only does 90 damage because it is "equal" to the HP of card I Top Dropped. I thought you multiplied by 2, because it is like doing damage that is already assigned on the card.
Please help! Thanks!
