This is our very first Manticore, and being a slightly-more-obscure mythological creature, I am so happy that Manticores were allowed to keep their race unique instead of being folded into the Sphinxes or something
It taps to add one colorless mana and also has an ability for three colorless mana and tapping to draw a card, but you can only activate this if you control a creature with power 4 or greater
when its defence hits 0, it exiles and you cast its back face for free
If you drew from other sources, you can choose to put those back instead of paying life
They are not so easy to find though and I doubt they will come up more than once a year
First, Chapter I lets you choose the most threatening noncreature artifact from each player to turn into a 0/4 Wall artifact creature with defender in the hopes that, once Chapter III comes around, you will destroy all of them (along with any other Walls around)
