Too Many Emojis

To start, we are provided with the following image:

From this image, we can see that we are provided with the flag format. By crosschecking the flag format bronco{} and the first group of emojis, we can see that the first letter of each emoji is used to make the flag! So:

Emoji	Emoji Name	Letter Taken
💔	Broken Heart	b
😌	Relieved Face	r
👹	Ogre	o
🤢	Nauseated Face	n
😖	Confounded Face	c
👹	Ogre	o

With that, we can get the flag!
