I wanted to see more interesting combos with Bug. At least they had one new combo with Ice/Rock.
Speaking of that, here's all the new type combinations we got this generation, including those that were created when old generation Pokemon were retyped to Fairy:
Normal/Ground (Diggersby)
Fire/Normal (Litleo line)
Steel/Ghost (Honedge line)
Dark/Psychic (Inkay line)
Poison/Dragon (Dragalge)
Electric/Normal (Helioptile line)
Rock/Dragon (Tyrunt line)
Rock/Ice (Amaura line)
Fighting/Flying (Hawlucha)
Electric/Fairy (Dedenne)
Rock/Fairy (Carbink)
Steel/Fairy (Mawile and Klefki)
Ghost/Grass (Phantump and Pumpkaboo lines)
Water/Fairy (Marill and Azumarill)
Normal/Fairy (Jigglypuff line and Azurill)
Grass/Fairy (Cottonee line)
Psychic/Fairy (Ralts line, excluding Gallade and Mr. Mime line)
Fairy/Flying (Togetic and Togekiss)
That's actually a good amount of new typings we got this generation, especially a lot of ones involving Fairy-type.
