Other than Black Hole, some alternative ways is through special Seal card draw (You draw on Friday, gives you this bonus card), or through Boss stage's achievements clerance, or even on certain Biweekly Lost Relic stage.

Sometimes on a new week, MH even create new easy stage (one-off) for farming these PR material.

Eh, but those event is totally controlled by MH, so yeah, I think the only always-available stage is through Black Hole only.
