In LCV Emrakul the PEL is a real card. I have seen it being played more than once (I even lost a close game because of it). In the hardest control deck this is another control card payable with colorless mana, and not too much (average cost is 7 after graveyard reductions). Even if it gets countered/removed, the effect stays and can provide decent advantage. If not, there you have a huge creature that skips moat.
Not a card for any deck, but if you want a finisher in Landstill, it's probably the best.
