The only degenerate deck there is Big Priest. The others are just extremely powerful.
If you lose by turn 5 it means your opponent had a godmode mulligan RNG, or you are playing too slowly/greedily.
PS: Jade Druid is t3 currently. Are you sure you know what you're whining about?

Too much Esports, not enough RNG.

Except, [card]Faceless Summoner[/card] can't summon anything lower/higher then a three drop.
Plus, it's a randow three drop, and with [card]Menagerie Warden[/card] you know what you get (even it it's a beast).
I think this card will work in a specific deck, but won't be broken effective in every deck (as 4 mana 7/7).

You should add murlocks and The Curator.
But seriously, you should make a deck list where you say all this and we can see whole deck more clearly. Plus, you should highlight cards (when you post something you can click on a card button and enter a name or use Card Name) so we can see text more clearly.
Good luck with this combo, though it would be hard to pull it out.

There must be diversity in the game. Plus, if you control deck cant counter early agresion than there is something you need to improve.
