Riding the Maelstrom

Riding the Maelstrom
Action
Harbinger of Skulls
Put this card in play with counters equal to the acting Harbinger of Skulls capacity and put them out of play underneath. If this card leaves play, put the Harbinger of Skulls in your torpor. A Methuselah may not control more than one Riding the Maelstrom. In your untap phase, burn up to two counters off this card to force your prey to burn 2 cards from their library or 1 pool for each counter you burned. Burn this card when it has no counters.

I get the concept but it feels non-interactive. In exchange for a vampire you can achieve the effect of: playing a slaughterhouse, playing an antediluvian awakening, or bleeding for 1-2 each turn.
