Internal Flicker At your 1st level you have enough of an understanding of how the flicker works to make it work for you. You can now, once per flicker level, flicker instead of moving normally. When you flicker you teleport to a unoccupied space that you can see, it does not incur attacks of opportunity. But you can only move 1 feet, per 2 feet of your accessible movement this way. You regain your flickers when you regain spell slots, if you don't regain spell slots, you will get them back after a long rest.

Sideshift At 2nd level, your knowledge of how to utilize surprise is expanded upon, allowing for far more deft attacks. During your turn, if you have been teleported by any means, your attacks have advantage and you add your proficiency bonus to both attack roll and damage.

Improved Technique At 3rd level you skill in using the flicker grows tremendously. When you flicker now it's range is now on equal to your remaining movement.

External Flicker By 4th level your competence is so great that you can bring it unto others. As an action you can teleport another creature of a size equal or lower to yours, this follows the same rules as moving yourself and still uses your movement. If the person tries to resist being teleported you must make a melee spell attack against them, if you miss they are not moved. Spell Attack Bonus = Proficiency bonus + Intelligence Bonus
