It's turn 10, Amaz has some small minions on the board and the Warrior has 24 life. That means NO CLOCK and the warrior has all the time in the world to piece together his combo.
In order to beat Patron, you need some combination of the following:
1) large beefy taunts (e.g. Handlock)
2) 3 damage board clears (Brawl, Hellfire, etc.)
3) a clock (Grommash, mountain giants, Highmanes, etc.)
which is why midrange Hunter, Handlock and Control Warrior all do fine against Patron.
A slow durdly Paladin deck is not a good choice because it has neither the clock nor the other things.
