Gravity Pull and Shriekers

[Pilchard123]

It's called Eternity/Rewind - hourglass - recast

Two cards for what should be, in my opinion, one card.

Also, it's called infection. Poison is what you put in your opponents' tea.

Whatever. I know what I mean, and I think you do too. But then I'm just as picky sometimes.

Immortality is not reverse compatible, if you will.  Immortality = untargetable.  Burrowing = untargetable.  Poison, gravity pull, freeze etc. = effects already in existence and applied, no longer in need of targeting.
