I have a card (forget name) that is6/6 with Stop:+4 Damage Lajunta and Bonus +2 damge witch makes it 6/12 but whenever i fight it always takes the ability away and people say something about SOA wht is that?
You mean Dacote. Stop: +4 Dmg means that if your opponent plays a card with SoA (stop opp. ability), your card gets the +4 damage added, otherwise the ability isn't activated. Basically it's the opposite of a normal ability.
Normal ability: stopped by SoA
"Stop" ability: activated by SoA
