So yes you can win I agree but we can't deny that expensive cards gives a slight edge

Yes, it does! But look at the overall stats of both my opponents' expensive decks: 17 wins and 11 wins. So as mine with F2P deck 17 wins. Card's price is not the one and only deciding factor. Good piloting a Lamborghini is as much important as having it.

Follow my new posts with more budget decks that have 24-22 wins at Mythic on Weekend. I'm planning to make such recap of budget decks every week.
