Pvp matchmaking... no chances to win

Not really. Just pick your battles. If PVP is hard try to snipe it (join a bracket at the very end - just in time to win 3-4 matches). Who knows - maybe you will get lucky and score some big covers/iso/hp. If not - better luck next time.
Do DDQ every day and play PVE to gain ISO, covers and HP. You will get there.
