Best advice is to purchase all the Arcades. You will need the Lds in ELO.
The credits used to purchase the arcades will be the same / equivalent as if you bought packs from the shop (with the LD cards as the bonus).
After purchasing the Arcades, just keep saving your credits until a new Big 5 (or close to it) is revealed in the New Blood Packs.
You could also buy the comics, but i'm lacking incentive. Might as well read up on the old comics before I plan on purchasing them.
I'm gonna be honest, the comics mostly suck. They were cool when they were free but the crappy artwork and amateur writing aren't worth paying for. Granted, I haven't purchased a comic since Room 13th, so maybe the artwork has improved. Nemo isn't writing them anymore either (R.I.P.) so maybe the writing's better, too. But that comic was enough to put me off for a good long while...
Thanks for the heads up, I checked the latest Raptors comics, and the art looks great. The stories, I can't say.
The free comics sucked and the art was very amateur. Only thing good about it was the foul language (that was eventually censored) lol!
Arcade is the best options for the reasons that others listed, but Personally the most important one is the free Cryptocoins.
Stockpile them up and wait until a big 5(or 4 now?) cr increase drop rate or if an expensive cr goes mt they always have a drop increase when they go mt and if you are lucky
Big 5/cr->mt drop increase + crypto pack discount
Thanks to the coins I got from arcade I got a lovely guru CR
