This deck tends to do pretty well against everything except aggro and control decks. 

Stay on the board, take good trades, and you'll be carried by your buffs in the late game.

Be strategic with your Seedcloud Buckler deathrattle.  Party up + divine shield can be devastating.  Claw Machine + divine shield is pretty cheeky too.  Plus, a bunch more.

Most of the time you'll want to hold your Blistering Rot until it gets buffed a couple of times.  This card has huge power potential and it works a surprising amount of times.  Even if the opponent deals with it right away, you'll still have the copy on board.  This card can turn the game in your favor or solidify your board lead.

I've found that the Libram of Justice + Consecration combo is necessary in some matchups.  Of course, you could sub Equality for Libram of Justice, but that weakens your board, so I don't like it.

You might be temped to save Hand of A'dal for Blistering Rot or Crabrider, but it's often better to use it early to control the board and draw more cards.

Mulligan for Aldor Attendant, First Day of School, and Costumed Entertainer.  Don't keep Libram of Wisdom unless you already have Aldor Attendant in hand.
