One: Muster for Battle
Muster for Battle is not only the strongest Paladin card, but also the strongest card in arena, period. Including legendaries. That’s right, you heard me. A player who plays Muster on turn three will typically beat a player who plays Dr. Boom on seven. The reason for this is purely the early game control it gives. It comes in and gives the Paladin the ability to attack immediately. Then it has also filled the board. The 1/1s synergize quite well with many Paladin cards as well. Because of how many weapon charges are given, Muster far outperforms its cost. It is essentially seven damage for three mana, an over performing Fireball.
Again, the only downside here is that Muster for Battle is a rare. You should not even think whenever you see Muster, simply take it. Being able to play it on turn three is such a game winning play that it is worth overloading your deck with early cards by taking more of them. It is a rare time indeed that someone plays Muster on three and loses with the best card in the game for arena.
