Matches are usualy cheap,so they are easily played.You have to have a match in play to have this card do anything,but that's not a huge price for what it does.For 4 power,you get a card that deals 3 damage after each players turns.That's 6 damage between your turns.4 power usualy will get you 2 damage for a permanent card(creatures,items,etc.),like Boa Constrictor.This is a good bargain,heck,it's an awesome bargain,but theres still the problem of having a match in play.Use a cheap one,Slytherin Match is realy cheap at 1 Qui. power.It's gonna take about 2 turns of punishment for this one to get solved by your Bludger,and possibly creatures you have.All the better.....Slytherin Match lets you shuffle 15 non-healing cards into your deck.Quite a big life advantage.
