General Mulligans
These are the key cards you need for your early game dynamic - Fire Fly and Arugal to make sure you have elementals to trigger later battle cries, Shimmering Tempest to get your random spell generation going, and Arcanologist so you can get your secrets out of your deck and onto the battlefield. All of them provide solid board control against Aggro and Midrange, and against Control provide early pressure that could snowball unless they have answers.The idea here is to use secrets for defense, minions to control the early board, and then the massive value generated by Frost Lich Jaina and Greater Ruby Spellstone (upgraded by your elemental plays) to close out the game.
