Spellstones enter the hand at their final upgraded state

I specifically noticed this with the Druid spellstone, e.g. if the spellstone is played at level 2 (deal 4), it appears to be drawn that way, and does not change when armor gain effects are played.

This is a general issue with cards that transform in hand (Spellstones, but also Unidentified Items and Worgens). They need some custom, card-specific logic.
