Elenda dies into a Vampire for each point of power, three times as many with Ojer Taq. Phyrexian Altar turns Elenda and the Vampires into the plus tax to recast it, and every Vampire sacrificed after that puts a +1/+1 counter on the new Elenda. From 2 power plus one for each earlier cast, Elenda's power nearly triples every loop.
