>>32834363Kanata and Irys are 4/4 flying Angels because that's the most common Angel token. Nephilim is a valid Magic creature type but nothing specifically makes tokens of them. I originally had Irys be a 3/3 black Angel to have some of her dual-nature theme going on, but only one card makes that token and it gives it to your opponent. Boo.
Kiara's the red bird because it's no fun to just have her temporarily sit around as an elemental on the off chance she might bring back another phoenix that technically isn't even her.
