Thawing Mountains and Corolla

[rich flicker]

So recently I was playing against darkworld with my EARTH Fairy deck. I had Vernusylph Corolla up and just added Thawing mountains. Why couldn’t I use Thawing mountains while it was the only card in hand (yes I checked and no I hadn’t used Corolla yet)
