The Crazed Alchemist can be used at any portion of the game. As early as turn two, it can be used simply to turn a minion that has 2 / 3 into a 3 / 2 minion so that it can trade with it. If a player has no other option, this will result in a fair trade, however some players may prefer to hold onto the card to increase it's value even higher.
On turn three, there are many minions that only have 1 attack and a higher Health Pool such as the Acolyte of Pain
which is a 1 / 3 minion.
The Crazed Alchemist can use it's battlecry to change these minions into a 3 / 1 and then again be able to trade with them which is a positive trade as the player is trading his two mana minion with the opponents three mana minion.
It can also be used to swap the Attack and Health of your own minions, for example a Core Hound
which is a 9 / 5 could be changed into a 5 / 9, making it a more beefy minion still with a decent attack value.
The Crazed Alchemist often finds home in many Priest
decks due to it's synnergy with some of their Cards.
In a Priest Deck
that has Inner Fire
or Divine Spirit
, lots of combo's with different minions can be used alongside the Crazed Alchemist in order to swap minions statistics resulting in very beefy or very high attack minions, or both.
Another card that synnergizes with it well from the Priest Cards
is the Cabal Shadow Priest
. The Cabal Shadow Priest
can steal an enemy minion of the players choice as long as it has an Attack of two or less. If for example, an opponent had an 8 / 8 minion, a Priest could use his own minions to reduce the enemy minions health to two points, turning it into a 8 / 2 minion and then using the Crazed Alchemist to swap these values, making it a 2 / 8 minion and then finally using the Cabal Shadow Priest to steal the enemy minion as it now has only two attack points.
