Strategy
Oracle has access to both basic and strong dispel on offense and defense. Look to dispel spells, items and runes that provide buffs or debuffs.
You can deny your own creep by nuking it with Purifying flames and quickly attacking it afterwards.
Oracle has a huge powerspike at level 3 with one point in Fortune's End and two points in Purifying Flames. Combine Purifying Flames followed by Fortune's End, and another Purifying Flames before Fortune's End lands on the enemy hero.
It is good to carry a 
Healing Salve to use it on the ally that you save with False Promise.
You can channel Fortune's End on your nearby ally who is channeling 
Town Portal Scroll, or about to 
Blink Dagger away, and the Fortune's End will follow that ally.
If you expect to be silenced in next 2.5s, you can start channeling Fortune's End on yourself and as soon as you get silenced you will dispel it instantly with Fortune's End release.
A well timed Fate's Edict can entirely negate the damage output of heavy magical spells like Reaper's Scythe, Finger of Death, Bedlam and others.
Position yourself outside of the opponents' vision at the start of a teamfight as you are usually the main target.
Items like 
Aether Lens or
Blink Dagger allow you to get a timely False Promise off. If you False Promise yourself, you can blink out even under attack as you take no damage.
You can spam Purifying Flames on one of your allies prior to a fight to provide some extra healing going into the fight.
When breaching or defending high ground, put Fate's Edict on your front line ally along with a couple of Purifying Flames to protect them.
Counter Strategy
Oracle's Fortune's End applies dispel. Use your dispellable buff or debuff spells after it has been used.
Oracle's Fate's Edict negates all magical damage. Do not waste your magical damage on it.
Focus Oracle in the fights as he provides saves and sustain for his team.
Items that reduce healing and regeneration are good against Oracle.
Gap closing items allow you to get on top of Oracle.
The enemy mid laner will know where the power rune will spawn because of Oracle. You can follow him to contest the rune.
