Although luck is still the deciding factor, the pull rate of r3s and r4s have gone up, due to the introduction or r5 cards. Eventually, you will pull one. You probably have noticed however that the r3 pull rate has gone up also. For me, every 50 cards, I get 4-7 r3 cards on average. During the time from my other post, I got Galvatron's weapon too. So there is definitely a good chance to get one. Just keep pulling medals, you will find them eventually.
