To start, you'd need token generators like the following.
- Master Splicer
- Blade Splicer
- Attended Knight
- Scion of Vitu-Ghazi
- Captain of the Watch
- Courser's Accord
- Midnight Haunting
- Knight Watch
- Trostani's Summoner
With cards like that it provides a good base of token creatures as well as some support (the Splicers bonus abilities make the golem tokens better and Captain of the Watch makes the soldiers better).
To make the deck better it needs some good support cards. Usually things that globally pump creatures or make more tokens. Once the core token producer cards have been taken, support cards like the following are drafted next
- Spear of Heliod
- Phantom General
- Victory's Herald
- Collective Blessing
- Rootborn Defenses
- Wayfaring Temple
- Trostani's Judgment
At some point though you need something to bust through so a few finisher cards are necessary. That's part of the reason to grab a card like Victory's Herald that can make all your tokens flying. Similarly a card like Predatory Rampage can be enough to force through enough tokens for the kill.
This archetype is fairly obvious but for some reason no one but me seems to draft it whenever we draft the cube. Tokens is a lot of fun and if allowed to grow their army, hard to stop.
