Just showing off my largest gear expendable yet - F2P mass spending gear for SLK prereqs

so how does he get so many relic toons - I have been playing for every single day for nearly 4 years now and I am no where near that many. I take it he hasn't spent anything for sixth months but he would have had to have blitzed it before - but without spending??? I'd like to see your strategies to 7* toons and then Relic them...please as I could do with some advice.
