You can buy wins, draws and extra matches using points (by pressing
in the main menu).
You can't get the achievement just buying wins and draws, you must earn your last point playing a match, so the easiest method is to buy 3 wins and 2 draws, then you'll just need a draw in a played match.
On my last match my (losing) rival quitted after 70mins, nonetheless I got the achievement.
PS: You can gift wins/draws/additional matches to your friends, it will cost 50% less.
