I don't get why Blizzard keeps making cards with a fixed mana cost that have slightly-below-curve stats and a condition that buffs them to slightly-above-curve stats. Cards like Blackwing Technician, and now Shado-Pan Cavalry and Master of Ceremonies.
That kind of design just seems excessively cautious. The result, in my opinion, is boring cards. If you're going to do a card that's nothing but pumped-up stats, at least make it so that the theoretical best case is crazy, like with Frostwolf Warlord. Would Master of Ceremonies even be broken if she got +2/+2 _per_ spell damage minion instead of just once?
Yeah I sort of feel this way too. You jump through hoops to get like a 1-1.5 mana boost in stats when the payoff isn't even that great compared to cards with crazy abilities, especially at the higher mana level as is the case for Shado-Pan Cavalry. At three mana though, it's not so bad to have a "stat monster", as early on you just want stuff to give you the initiative. Like, I don't mind Tinkertown Technician or Blackwing Technician since they at least fit it with a a novel theme that's core to their expansion. Each expansion should have a couple of those.
This card though, Master of Ceremonies, like why spell damage minions? The spell damage minions pay a stat cost, but you should be making up for that with spells, not a minion that makes you break even stat-wise.
Anyway 6/4 with a conditional effect is already covered by Volcanic Drake. By the time you can reliably make use of its bonus, 4 health minions aren't all that great anymore.
