Abilities Class

Hello  
I am going through this tutorial and tried to implement multiple abilities and found this


2. You could create a new aspect, perhaps one called "ability container" which holds an array of ability. Then the ability wouldn't need to be an aspect itself. Just make sure all cards have this aspect, and when adding the ability to the card, get a reference to the container and append it to the array.


this is what i have so far - i chose to use a list instead of an array not sure if that matters - i know there are differences but i dont know all of them so i may not know that i CANT use a list in this situation.
 

bit confused on assigning the card to the ability and how to proceed with this
 

democards is read
multiple abilities array json  is converted to abilities list with object Ability
a card has a list of abilities
check for targets and add the targets (not sure how multple abilities with targets will work - would have to modify the clicktoplaycontroller alot i think for that but for now carry on)
the abilities are carried out in sequence
game continues

its complaining about reference errors - i am pretty sure it is because the ability class card is being referenced and it doesnt have anything assigned to it.... im not sure how it gets assigned 



any help would be greatly appreciated.

 code i changed:




{
"id": "Card4",
"type": "Minion",
"name": "Grunt 2",
"text": "",
"cost": 2,
"attack": 3,
"hit points": 2
},
{
"id": "Card5",
"type": "Minion",
"name": "Rich Grunt",
"text": "Draw a card when summoned.",
"cost": 2,
"attack": 1,
"hit points": 1,
"abilities": [{
"action": "DrawCardsAction",
"info": 1
}, {
"action": "DamageAction",
"info": 1,
"targetSelector": {
"type": "RandomTarget",
"mark": {
"alliance": "Enemy",
"zone": "Battlefield"
},
"count": 3
}
}
]
}
