Not only do they stack, but from what I've seen, they seem to be multiplicative not addative.

So, DON'T add your bonuses (25% + 25% + 15% + 15% = 80% bonus)

Multiply them (1.25 * 1.25 * 1.5 * 1.15  = 2.066 or 106% bonus)

This makes a big difference when you have a lot of bonus cards in your deck.
