I'm not really sure if the Upgrade is powerful enough - + 1 HP doesn't seem to justify not changing the cost. Possibly make the upgraded Dragonling's stats 2 | 4 or lower it's cost by 1 quanta?
Ah. Then perhaps you might both change it, and have only one copy of the card on the field at one time. or you can only summon one per turn? Yes? no?That would prevent spamming.
So this card allows for more than six dragons then?Because you can have the six dragon cards, plus six dragon scales?Is that right?
Ok. But perhaps you might increase the cost of the inital spell, and decrease the cost of the dragonling by the same amount, just to even it out a bit.
