What is your favourite team composition/individual card ability and why?

Hello everyone,

My name is Alun, also known as Big Al and my splintertalk alias Bigaljaho. Today I was battling and realised that all too often I have 2-3 cards with the same ability in my team. Now often this can be beneficial and other times not so much, but it got me thinking , in your opinion what is the best ability team composition and in what order? I usually like to have a card that either provides a melee or armour buff, a tank with the 'Shield' ability, a tank healer and usually some little sneaky assassins with my favourite ability of all 'Opportunity', I usually finish the composition with a back line tank or a ranged card with a decent health stat (occasionally an extra tank with healing abilities such as Cerberus), so all in all, what is your favourite team composition when it comes to abilities? And what is your favourite solo ability and why? Looking forward to hearing your opinions, much love..Big Al.
