Strategy
Apply Aphotic Shield pre-emptively on yourself as you are coming to lane after rune fight. Apply another as the previous one expires to inflict great AoE damage. Pull afterwards.
Play ahead of the Core you are supporting to absorb damage and trade regen.
Healing Salve or 
Clarity won't be canceled while you have Apothic Shield on.
If someone applies a break effect on you, you will have to trigger Borrowed Time manually.
If you got disabled along with your teammate you can pop Borrowed Time to remove stun off yourself and then apply Aphotic Shield on a stunned ally to free him as well.
You can position more aggressively than rest of your team, as opponents usually don't want to go on you due to Borrowed Time.
Constantly look at your teammates to heal or hard dispel them.
Silences and heal reductions are a big problems for Abaddon. Avoid being hit by those or itemize against them.
With 
Aghanim's Scepter, you will need to activate your Ultimate manually, while most of the damage is being inflicted on your teammates.
Counter Strategy
Abaddon's Aphothic Shield applies strong dispel. Use disabling and damage-over-time dispellable spells only after the shield was used.
If you are in the fog, exploding Aphotic Shield won't damage you.
Abaddon's Ulti Burrowed Time applies strong dispel and heals Abaddon for all damage taken. Don't hit him.
Break effects make Burrowed Time not start automatically. But Abaddon can still activate it manually.
