What are bolas and what are they for?

Tezzeret Agent Of Bolas + Liquid Metal Coating + Phyrexian Metamorph?

• So, what happens when you make Tezzeret, Agent of Bolas a creature with liquid metal coating, then use the -1 ability to permanently make him a 5/5 artifact creature. If you copy it with Phyrexian Metamorph, does it kill Tezzeret? Also, if it does not kill Tezzeret, can it use the abilities too?

• Answer:

  If you turn Tezzeret into a creature, it becomes a 5/5 Artifact Creature Planeswalker - Tezzeret with whatever Loyalty Counters are remaining on it. Any time it takes damage, it will have that damage sit on it like a creature *and* remove that many Loyalty Counters from it. This means that he can be killed by enough direct damage to kill a creature, a Destroy Creature effect, a Destroy Permanent effect, or losing enough loyalty though damage sources to have no Loyalty left. If you make a copy of Tezzeret with something like Phyrexian Metamorph, you would then have 2 Planeswalkers of type Tezzeret on the battlefield, so they would both go to the Graveyard before any player gets Priority, so you would not be able to use an ability on the copy.
