Stacking Counters?

[Shiro]

So I had a random thought. What would happen if I put Counter Attack, Counter/Death Blow, and Magic Counter/Contain on a character? I wouldn't dare dream that he would do all 3 attacks at once (though I suppose it's possible). So what happens? Does the game just pick one at random, or is there some priority system where it'll always do the same one, but never the other two?

it will use all three assuming you have mastered the counters :)
