Okay sure, and turn 2 Mechaz0r!s happen as well. But does anyone leave a game like that feeling good about it, win or lose? 
I just don’t know that adding more of such stuff is a good thing. Especially when it’s not even a combo, it’s just “pull it and play it” and if your opponent has no answer, the very next turn he has to deal with potentially absurdly overpowered minions for turn 3. Unless they change what Burst can summon, I suppose.
We only have 5 days to wait and we’ll see everything and how it fits together. I am just puzzled that people think it would be a good thing for a player, on his/her turn 3, to have to deal with 4 eggs scattered around the board, each of which can potentially turn into something costing more than the player could cast on turn 3. There are AoE options in the game, but not many, and even fewer that can be played that quickly.
Having to deal with a makantor, a silithar elder and a kolossus on turn 3 is not really comparable to a buffed lion, is it?
