Delver Zoo aka Wild Secrets

[Pedros]

Here is a deck that has some results on mtgo. Curious why it doesnt run Tarmogoyf. Thoughts?

As some of you might remembered I tested Delver + Nacatl combo before and was impresed with them, couldnt play them on mtgo as I didnt have goyfs out there. I aw that this deck doesnt even run Goyfs, we however see
lavamancers and geists here. Thoughts?

I think it must be budget constraint or the need to play more then 1 spell per turn.

I'm also a huge fan of URx tempo builds in Modern my ONLY complaint is that I couldn't beat Jund or Junk at all.... (that said since DrS is banned it should be easier).

It looks like Tribal Zoo without Tribal Flames or the fifth color. Seems suboptimal.

[Pedros]

Didnt tribal zoo also run Goyfs?

Also isnt remand good in a tempo shell? Land cheap threat in delver, nacatl or goyf and protect it?

I dont know if Geist is good in either combo metagame (where tapping out on turn 3 sometimes means gg) or in grindy metagame (where geist is killed with anything that can block it).
