Three: Sunwalker
The old god of arena, the Sunwalker. This card is a well-known favourite of many arena players. Despite it being overshadowed by some of the newer minions like Bog Creeper, Sunwalker is still a good, reliable choice. In the worst of scenarios, it will eat a small minion or a hero power and then another minion, but in the best case it will kill off two large minions before falling. It’s a great way to stop an opponent’s charge, while once again providing a strong enough body for a counter-push. In many scenarios it will only end up eating your opponent’s hero power, but that’s still a two mana cost just to get rid of the divine shield.
Sunwalker is not an incredibly aggressive card. It can certainly protect smaller minions if you want to play it in an aggressive deck, but for the most part it’s better in slower decks. Similar to Bomb Lobber, it goes well in Mage, Druid, and Rogue for their ability to kill off low health targets before they can pop his shield. He also works well with Druid, who enjoys ramping into large taunt minions.
