In iOS 10, the QuickType menu is a lifesaver whenever the user needs to type a long word and doesn't feel like typing it (and it's also fun to make up silly sentences).
It also randomly suggests Emojis. But finding what to type to make the intended Emoji appear can be quite discouraging. For example if I want to type the "Smiling Face With Horns" 😈 there doesn't seem to be a way to QuickType it without having to go in the Emoji Keyboard. See examples below showing attempts at entering "Demon", "Evil" and "Devil":
Can all the Emojis be called through QuickType without having to go into the Emoji Keyboard?
How do I know how what to type to call the right ones?
