4* Enraged Arlong 41
4* Baloon Luffy 23
4* Arm Point Chopper 20

Also got a rainbow dragon (INT, 1500HP 800ATK) if its important.

I got Lvl 9 Merry Go and 88 Cost to spend. I also got about 7 Gems to continue if its needed and if I get him then I would do it.
I really wanna have Garp because he is such a great unit
Thanks for your help.

your int units are to weak but i think you can do it with 3 or 4gems to revive
depending on orb luck

g3 friend
g3 captain 
robin
nami 
rainbow dragon (i think he stonger then the rest of your int units)
buggy

first fruit you would have to use at coby stage 
after that if you managed to save three int orbs and robin
special is ready you can do like 1 million damage
then you can hit him for two times before your hp is gone
you can hit him for 560 k with neutral orbs
here goes the second gem and again you have two hits 
with neutral orbs like 560k and you have to use the third one
and this should be the turn where you finish him
 
if you miss one perfect or you have bad orbs you will need fourth gem

i would spend the gems in gettin garp
