Warrior Exclusive Skill Cards Show Up
His hero power could not restore any HP or damage any enemies on the board, while his +2 shield could help you much if you combine it well with exclusive skill cards below:
Battle Rage (Draw a card for each damaged character.)
Many of Worria’s skills are triggered by wounded minions. It was 2 mana before Closed Beta Patch, but now it costs one more and damaged heroes are also counted. Since we usually play it as a later game card, it doesn’t matter for most players to cost one more mana with heroes counted, which means the more wounded characters on the board, the more cards will players draw. If both you and your opponent have a lot of minions on the field, you could play Whirlwind in conjunction with Battle Rage and possibly draw a substantial amount of cards. However the effect would be discounted, if players always grant hero power in each round.
Brawl (Destroy all minions except one. Chosen randomly)
No doubt that it is a wide AOE and game-ended cards. For most players, dropping it at a negative situation would be the last chance to turn the game. Since Rush Deck and Murloc Deck are quite common, you can drop in the T5 (4 if you're lucky and draw The Coin) which is a burst turn for them, making a board clean. Also you can save it for the later, dropping it when you think you have to. It needs to point out that Brawl will randomly leave a minion on the board, which means the core card of your opponent may not be removed from the board, making a tide pressure for you in the next turn.
The advantages it brings are fairly self-explain. Usually it could combo well with Mana Addict, Questing Adventurer, or any minion with Windfury without any mana cost in current turn. Either way, players also apply it on some large minions making a game point or used early/mid game to help clear your opponents’ side of the board.
Not only does it boost the capability of these minions at no additional cost but it allows you to get some major hits in before your opponent has a chance to react and take them out. For example, you can play a 1 damage 3 health Mana Addict for 2 mana, Charge for free making it a 3/3, Inner Rage for free making it a 7/2, then Rampage for 2 mana making it a 12/4 monster that can swing immediately and your opponent is powerless to stop it, all for 4 mana.
Cleave (Deal 2 damage to two random enemy minions.)
There is also a restriction which may not be obvious to all players. If your enemy only has one minion on the field it cannot be used as it cannot target a hero or friendly minions. Therefore, there must be 2 or more minions on the enemy field for it to be used. With only two mana cost, it could remove most minions played in the early and combo well with Execute in the later.
