Pros           Teleport units into battle.     Spend money easily.     Observer = best scout
Cons                   Least amount of variety

Toss units and structures

Zealot          like sc2 a frontline attacker. Bonus vs bio. charge is just stats
Stalker         like sc2      a easy to micro unit that can trade well if controled
Immortal      half sc2. Good vs protoss and terran Mech. Otherwise too Expensive.
Dark templar          Punishes lack of detection. Come back or win games very quick.  
Archon         Powerful pscionic aoe bonus vs biological. (Good vs zerg and beast)
Observer      Can purchase detection. Invisible spy.
Mage            slow fragile mage with powerful aoe including regen+armor spell. 
FighterJet
Tempest       working on it

Ancient defender              Excell vs air and stealth. Buy regular towers vs ground
Warp gate                   Units are more expensive if warped in.
Achedemy                 recommend to research blink and charge every game.
Forge                This race benefits well from winning fights and suffers extra from                                         loosing army. Balancing upgrades with units advised.
