Your land count is too low for a CMC over 3; I would bump it up to 35-36 and then see if you can cut one or two (depending on mana dorks and mana rocks). This seems to be a common problem with new deckbuilders.
Admittedly, I haven't looked too closely at your creatures, but a cursory glance reveals a lot of creatures that don't have real token synergies.
Tolsimir's token is legendary so "populating" it is a bit useless.
Phyrexian Rebirth is a better board wipe than
Fated Retribution in this case. It'll leave you, in all likelihood, with a massive token you can replicate later.
Have a look at the
Rhys the Redeemed EDHREC page to see what kind of creatures work best in this kind of token generation deck.
