Summon two copies of taunt card, death nite

Each taunt card does 2 damage with a death rattle.
How do you even defeat these low card boogies where they keep the board covered until they can buff everything up to 1 billion damage by turn 4 or 5? Even if you keep wiping them out the board stays covered so they have to do is keep getting their buff up to a billion damage cards.
Can a dev explain what defense i need?
