Finally a return to the at least somewhat-interesting of Tavern Brawls. No random decks. Still a somewhat significant randomness factor, but at least it's somewhat consistent. Much better than the fare we've had for about 2 months now.
All minions you play that cost 2 or more gain a deathrattle of "Summon a minion that costs X, where X is the mana cost of this minion -2". If you reduce the mana cost of a minion below 2, it does not gain this deathrattle.
