So how will Chaze fare in this new meta?

I see chaze as the 'new' wiggs. They could be plugged into many teams and work out well. Even help a current meta stay relevant into the future.

3 phoenix, chaze
Nihilus lead, dooku, 3rd sith, chaze
Rex lead, gk, 3rd unit of choice, chaze
GK lead, jka,zarriss, chaze

They have great utility which I think will keep them relevant for a little bit.
