The main use of this card is not mentioned in a comment yet so I'll add it here:
This card is a must-have alongside Holy Spear. Indeed, using the big attack of the Spear forces you to seal an ever-growing amount of tokens on it, with no means to return them either to the bag or to the token pool.
Well look no more, seal tokens on the Spear to get high attacks, and free them to remove 1 Doom. It's literally a double bonus.
And secondly, if your teammate(s) are using curse in their deck, there is an obvious combo with Tides of Fate to clean a big number of tokens in one action with one doom removed.
This could for example be a good way to get rid of 5 tokens sealed on Holy Spear and 5 sealed on Dark Ritual, or with someone that would break the vow of the Geas
