You CAN Play Type I #78: Looking at Legions, Part I – The Mechanics
“Morph trigger” is actually Echo in reverse. You get the ability and a creature by paying a lot of mana spread over two turns. Now, compare Bone Shredder to Skinthinner. With the Urza’s Legacy predecessor, you get the Terror ability you need up front, then decide if you can spare 2B for a puny 1/1 next turn. With the new Legions version, you have to pay for the 2/2 before you can pay 3BB for the Terror you really wanted.
