Sorry, my connection was glitching.

Corpsejack Menace is bonkers, and other than that, I dunno, try searching Scavenge cards? And a few green creatures with evolve? I usually find new cards by using deck search with keyword about whatever theme I'm trying to play into.

Just trying to look through cards I've used in various +1/+1 decks-

Abzan battle priest, Tuskguard captain, and abzan falconer? Was kinda surprised they weren't here already, for outlast.
Enduring scalelord from Dragons of tarkir?
Retreat to Kazandu from BFZ is a fun one. Makes getting lands exciting.
Experiment One is a green 1 drop with evolve that can be pretty fun.
Reap What is Sown from Theros block is a +1/+1 sorcery.
For Golgari, Varloz, the Scar Striped gives everything scavenge, which is useful forgetting +1/+1s out of your dead things.
Renegade Krasis would be evil here. And Adaptive snapjaw would become pretty big.
Here are some Golgari tricks- Deadbribge Goliath, Dred Mangler, Necropolis Regent.
Increasing Savagery is good. (i'm looking through EDH decks, this is slow-going)
Inspiring call, Solidarity of Heroes, Blessings of Nature. All solid, I guess.

Once you add lands, I don't know how many more cards you'll need. Only 20, at absolute most. If you're focusing on +1/+1 counters, and appear to be going outside the usual Tarkir block fair, there are good Green cards from Return to Ravnica about +1/+1 counters, like some green evolve creatures, or Golgari tricks, like Corpsejack Menace.

I believe the card I'm thinking of is 'Bone Splinter'. Fits the theme, powerful card. Might be good here.

You have this deck tagged as token: I think what you mean is +1/+1 counters. Token usually means creature tokens. I mean, I guess morph is similar, but it usually refers to something else.

For extra counters, I like Cached Defenses (Bolster 3).

I suggest adding Hero of the Parrish. White 1/1 1-drop that gains a +1/+1 counter ever time a human enters the battlefield under your control. Get it out early, and it will snowball as you play more creatures.

I feel like Trostani doesn't offer anything that can't be provided by Vitu-ghazi guildmage. The lifegain when creatures enter is nice, but the guildmage lets you abuse populate with a lot more of your mana. Either way: I feel like Vitu-Ghazi guildmage would be a welcome addition to the deck.

I recommend Fathom Mage, and maybe Ponder? I dunno.

A recommendation: Edge of the divinity. If creature is White, +1/+2, if creature is black, +2/+1. for One white or black mana. Great for extort.

You probably want to have a full 4 Aquitects, otherwise islandwalk doesn't do you much good.

I haven't actually played one of these yet, so I'm going on what looks good on paper, but it might be good to try either shriekgeist or paranoid Delusions for some mill every turn.

Having that many Vosk Mind Drinkers is a little of a waste since you can't have multiple of the same legendary creature on the field at once.
