Tokens decks I've found are always fun decks to play.  Making a huge horde of creatures and then just overrunning your opponent always appealed to me so I made a concerted effort to include enough token generators and token helpers to make Tokens a viable archetype in my cube.

To start, you'd need token generators like the following.


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
This gives the deck a lot of punch as the Spear of HeliodPhantom General and Collective Blessing make each token scarier.  Those 1/1 birds suddenly don't look so tiny with pump effects like that in play.

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.
