You need to check your cards against the current ban list card destruction is a banned card this season.

You are trying to do too much: such as stalling.

I would take out all the stall cards (such as Destiny Hero Defender) and add in draw cards + Engine (such as Blue Eyes/Dark World).

This is a very basic build skeleton for you to start.
