It will be hard for them, there's only two majors for this season and they didn't even make it with any of those. The huge point for DPC has already been taken away from them. The last major is the Animajor which had already secured its playoffs, group stage and wild card seeds. There's no room for OG but there's still one more chance and that's why I've said it's hard for them. But I'll tell first that there were already 4 teams that are secured to play to the upcoming TI10 namely, EG, IG, VP and Team Secret. And for OG, they need to win the one slot of Western Europe qualifiers. But look at their opponents for that 1 very slot: https://liquipedia.net/dota2/The_International/2020/Western_Europe
