Its a good dragon.The upgraded one has good artwork,but should The upped dragon have like more HP?And jus 2 more attack?
It keeps it under the Gravity Shield's effect so I think the no Hp increase is ok. Could increase the attack just a little more though! ^^ An untouchable source of 10 damage is still better than an untouchable source of 8 damage =D
6 HP gets blocked by gravity shield 
Yea, just noticed, I wonder, would Zanz make it 12/5 if I asked?
Cause the Light Element's weapon doesn't cost much (Around 5

if I remember right) and it normally does 7/8 when upgraded. Also, it's initially untouchable so it's kinda a cheap immortal weapon, creature if it's animated( and total cost is still 7 which is low compared to the normal phase dragon).
