I'm gonna play OldTrees here for a bit on the cost issue.
Cost = Attack power + Skill cost(active + passive) + HP(0-5 free +1 per upto each 5 points after) + Element bonus + Upgreaded(if uped)
unuped
Attack P = 0
Skill cost = 5(based on FireFly Queens break down)(FFQ's skill is worth 3 because it's off element and cost)
Hit points = 0
Ele Bonus = -1 (Life creatures are 1 cheaper)
so finial cost for unuped is 4
uped
Attack P = 0
Skill cost = 6(it gives a stronger creature with each turn so +1 cost other wise same as above)
Hit points = 0
Ele bonus = -1
Upgrade bonus = -1
so finial cost for uped is 4
So based on current standing 4
| 4
Cost with this card really depends on what you this the Skill cost should be worth.
Now enough of me chaneling OldTrees.
I think the the Seed | Bud skill should be a Pay to generate like FFQ's (only with
) and the cost cheaper as it really is a weak creature skill aside. Overpowered this creature is not.
