Description for the use of individual cards and mulligan against each class.
The goal of the deck is the same as every control deck, win in the long game (even make it to fatigue) with your resources and control-style cards, although, you have to be careful with the use of your cards, because you only have one copy of each to make Reno Jackson work.
Use of some cards:
Sir Finley Mrrgglton has one of of the most unique effects in the deck and has to be used in the right time and with the right hero power.
The reason to change your hero power is that you won't need your damaging steady shot throughout the game, so you want to change it to a more defensive one, of course, your choice depends on the deck you play against.
Against aggro decks: Lesser Heal, Armor Up are the best, but if the game goes slowly, Lifetap or Fireblast also an option
Against control decks: Lesser Heal, Armor Up are both really good, but your win condition is Lifetap
The most forgettable hero powers are Dagger Mastery, Shapeshift, and Totemic Call, but these are sometimes affordable.
Mad Scientist might seem weird with only one secret, but it still saves you the mana to play the secret and it's still a mind games with your opponent, because they have no clue what type of secret could that be and it is a great early game body on the field.
The last the card that needs some explanation is Alexstrasza. You have to decide it on your own, during the game, what you're using it for. To deal the max 15 damage to your opponent to lower him from 30, maybe in fatigue, or to heal yourself and place a huge and threatening body on the battlefield. It's better to play her with minions on board to put more pressure on the enemy hero.
Mulligan: You have to toss back your big minions into the deck and try to fetch for your early game such as Sir Finley Mrrgglton, Zombie Chow, Mad Scientist, Jeweled Scarab, Wild Pyromancer with the coin, and Animal Companion. Personally, sometimes I keep Reno Jackson in my starting hand if I face Shaman or Hunter.
Thanks for the attention everyone and wish you all to have fun with this deck! :)
