Not really sure why there are comments asking if it can "still be Grind 99" - nothing has really changed in terms of the availability of cards from the past. You still get 99s from grinding the Season XP reward path, potentially 99s from the extra bonus spins, plus you get a 99 from the Monthly Award program.
Speaking of the Monthly Award program, do you remember when the Monthly Award program actually cost stubs? You had to buy the 95, 97, etc. OVR players to collect everyone for the lightning reward. Now it's a grindable program.
And this new Future Stars program, it may not have an actual 99 at the end of it, so I can see the concern there. But if you equip the Tucker and Kopech captains, you actually have a whole lot of 99-type players (even using other Future Stars cards not in the program)
