Thanks to videos from PTR we have a look on all Cards !!! (for Example (Thanks KBT):

First off, Reloaded keyword means: Trigger this ability when the Unit is played adjacent to units with the Reload ability.
Example: NR Reinforced Ballista, Bronze, 4 Power, Deploy: Damage an enemy by 2, Reloaded: Repeat the Deploy Ability.
And looks like NR has synergy with: Armor, Trios, and interestingly, Units that has the same Power, Interesting Examples:
-Kaedweni Sergeant: 4 Power, Melee, Bronze, Deploy: Boost all Units with the same Power as this unit by 1, wherever they are.
-Blue Stripes Commando: 4 Power, Bronze, Summon this unit (only 1 copy), whenever a different Ally with the same Power is played and place it on that Unit's row, Trio: Create 3 base copies of this Unit on the bottom of your deck.
-Redanian Elite: 6 Power,, Bronze, Armor 4, Whenever this Unit's Armor reaches 0, Boost self by 6.
-Dun Banner Heavy Cavalry: 4 Power, Siege, Bronze, Deploy: Remove Armor from 2 Units and Boost self by the amount of Armor removed.
-Temerian Infantryman: 4 Power, Bronze, Deploy: Boost self by 1 for each unit in your deck with this Unit's Power, Trio: Set this unit to the same Power as the highest Temerian Infantryman in this Trio.
-Ves: 5 Power, Melee, Silver, Summon this Unit whenever you trigger a NR Trio ability.
And Leaders:
-Foltest: 3 Power, Deploy: Boost all units in your hand and deck by 2.
-Henselt: 2 Power, Deploy: Summon all copies of a Bronze ally to its row. (so current Reinforcement, while new Reinforcement allows you Play a Unit from your deck)
-Radovid: 3 Power, Deploy: Lock 2 enemies and weaken them by 4.
Edit: Also we have Gaunter O'Dimm's Gamble:
Guess whether the top Bronze or Silver Unit in your opponent's deck is higher or lower than 5. The consequences of winning or losing this gamble are written on the card.
