Impending Doom
The death trigger is where the design turns cruel, and it points wherever you aim it: three damage lands on the controller of the enchanted creature, so slap this on your own attacker and you pay the bill, but hang it on an opponent's blocker and the loss of life is theirs. The +3/+3 and the compulsory attack are not a gift and a cost in the mold of an ordinary pump spell; they are two clauses conspiring toward the same violent end. On your creature, the enforced attack strips your ability to hold back, funneling it into trades and blocks it might not survive and hurrying along the death that costs you three. On theirs, the read flips entirely: the +3/+3 becomes a downside you are handing the creature, and the mandatory attack a way to steer it into your defenses so it dies on your terms and burns its controller. Auras have always carried structural card disadvantage, since one removal spell two-for-ones the enchantment along with the creature; this one bolts a second charge on top, a burn that fires on any death, in combat or to a removal spell. That makes the numbers aggressive because the drawback is aggressive: a fast clock with a self-inflicted bill when it goes on your side of the table, and a piece of forced-attack removal-bait when it goes on the other.
