need help with cards

[AdamS]

i need some cards that put +1/+1 counters on creatures to go with a {Damia, Sage of Stone} deck but im not really looking for the scavage cards i have most of them but need more

my basic stratagy is to ger  {Corpsejack Menace} out and then proliferate all the counters

[particle]

{master biomancer}

[ApexPredator]

{Doubling Season}

[Gorzo]

{Vorel of the Hull Clade}

[AdamS]

{Vorel of the Hull Clade}

does the ability double the counters ir just add i

[Double-O-Scotch]

Effectively doubles...

[Ertai]

{Primordial Hydra}  LOL GG.

{Bioshift} + corpse jack doubles counters, throw in {tamiyo, the moon sage} for infinite uses.  {give // take}, {Blessings of Nature}, {kalonian hydra}.  Off the top of my head.
