Ichorid

[Popwar]

I've been trying to figure out how the deck Ichorid worked for a while, and I believe I may have finally figured it out! Though I do have one dilemma in which I can't seem to comprehend... what is the importance of the card Ichorid itself?  It's benefits don't occur until after your turn, and than you must remove other creatures as well. So what am I missing?
