Wild Secret Paladin (Season 62)

Call to Arms is a great card in almost every situation. The rest of your deck is very versatile in mulligans, but ideally you will be able to curve out a 1-drop or secret into one of your many 2-drops. 

Avenge is a very strong card, giving a minion +3/+2 stats for 1 mana, creating minions that are hard for your opponent to deal with early on. 

Noble Sacrifice is a great card to gain tempo against aggro decks and preserve your board.

Sacred Trial is a massively overlooked card, as it can often find large amounts of value in board-focused decks as most players do not play around it. 

Both Muster for Battle and Haunted Creeper can provide you with an early board to contest your opponents until you can reach your turn 6, 7, and 8 plays. 

Avenge can give you a massive and sudden advantage against other aggro decks, often able to turn around or generate a massive early lead.
