This is a blood ability that would be very useful in some situations, but not many.
First off, it only works if the opponent uses offensive spells, which care the only things Absorb Spell work on, and without spells, the blood ability are worthless. Then, regardless of the power of the spell, this user and the spell will be sent to the Abyss.
Worse yet, this is the owners choice, so cards like Masoleum of the Zombie Lord (2/DU) don't help. However, this can be an effective way to remove a spell from the opponent's use in a game (because recycling spells are a common tournament theme), and can save a realm from cards like Disintegrate (392/1st), Estate Transferance (437/3rd), or Creeping Doom (29/FR).
Therefore, this may be an acceptable trade for a player sick of facing nasty realm destroying spells, especially since there are no blood abilities that counter spells.
This might be seen in blood ability focused decks, but in very few other scenarious (other support card types have better counters).
