[BUG] Hogaak being unable to cast

[Notshauna]

Hogaak isn't seeing creatures that you can convoke as valid options to allow it to be cast from the graveyard. This can be worked around but it's extremely detrimental to the card's primary plan.

You can't spend mana to cast this spell.
Convoke, delve (Each creature you tap while casting this spell pays for {1} or one mana of that creature's color. Each card you exile from your graveyard pays for {1}.)
You may cast Hogaak, Arisen Necropolis from your graveyard.
