The answer is yes, you can. Here are ways to achieve this.
Be on a good team. By a good team, I mean one that hits the 8/8 team prize achievement and gets the level 10 chest without fail. It is second nature to them and not a reason to blink.
Be part of the good team. This means you pull your own weight on the team and don’t rely on your teammates to do the heavy lifting for you. Do your sh*t.
Have Atlas on this team. Kind of goes without saying, but it really does help.
Hoard those chests and rubies. Use these without any discretion at the beginning of the season during the two weeks of discount. It doesn’t matter if you’ll actually use the dragon or not. These are 50% off prizes that will stock up your stash of IF, energy, and timers through the rest of the season. Try to finish at least one discount line and a half by the end of the two weeks. I recommend not going below 30k rubies to open chests, but that’s just because I like a safety net.
After that, jury is split. Some say only open chests/use rubies during PVP events (this is because the contents of PVP chests are more valuable than fort/breed chests) and some say to not use rubies or chests until the very end of the season if you need to. Either way works, whatever floats your boat.
I tend to hoard all through the season and then splurge rubies on gold chests if needed during super sigil weeks.
In PVP and all events tbh, it really is best to push past that 8/8 score. Most say at least to the 450 sigil prize. As a free to play/elite to play player, I usually go to that point and then see if my resources will allow me to push further in PVP. In fort/breed it’s no problem.
Shiv made an excellent video on how to get a mythic free to play. It’s a bit outdated at this point because it needed fewer keys to achieve the goal, but the end result is much the same. See it here. Shiv does a lot of good stuff. Might be why he’s in one of those faction thingies.
I’m probably forgetting something because I’m apathetic, so if you see edits on this topic, that’s why.
STEP SEVEN [Optional]
I’ve included the optional step seven for those of you who like to be organized and whatnot. Use a season planner. Not just a season planner, but event as well. They have them for fort and breed and stuff like that. If you really wanna be anal about stuff, plug numbers into a spreadsheet and it will literally think for you. Another one of those cool awesome things Faction people have done. I personally don’t do this because numbers and I don’t get along well, and planning and I don’t get along well either.
