[ragnarok1945]

1st one is better suited as a Beast-Type, not Dinosaur, and it needs more effects while on the field

 

for the 2nd one, 3150 def is somewhat too high for lv7, I'd make it lv8 instead. defense position should be Defense Position

 

for the 3rd card, since you can't boost its stats, then it's considered too weak for a lv8 monster, even with 0 Battle Damage. I'd raise its atk power to around the 2400 mark
