During this turn, your active Pokemon's attacks do 10 more damage to the active Pokemon for each prize card your opponent has taken (before applying Weakness and Resistance).
Ability: Dual Brains
During your turn, you may play 2 Supporter cards.
If I use Iris twice in one turn thanks to Magnezone's ability, will the damage stack? Say my active has a 100 damge attack, and my foe has taken 5 prizes. Will he do 200 if I use Iris twice?
