The templating is also vague, does it get +1/+1 for each keyword it picks up, or just each creature? I assume the latter but the ability needs to have two sentences for that to be clear.
It is intended to get +1/+1 for each listed keyword the tapped creature has, and gain those keywords.

Tap another untapped creature you control: Observant Changling gets +1/+1 and gains flying until end of turn if the tapped creature has flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.

I'm going to drop myself, I didn't look at the previous entrees and didn't that Subject16 had already basically made the same card.Creature - Shapeshifter {R}
