Before I trade too hard for a new card, I sit down and look at the deck I want to put that card into
Journey to the mythic plane of Theros, where gods, heroes, and monsters abound
I do not want the deck to do only one thing
If you cast any removal on the Nephilim for example, his trigger copies it onto each and every targetable creature and then Pssibility Strom "cascades" it away which means your Nephilim lives another turn AND you'll get another free spell out of the deal
While seven total mana between its casting cost and equip cost are already much higher than they should be for the damage the card can deal, the card is made infinitely worse by preventing the quipped creature from untapping
X , he can be a great attacker as well
