T1 land drop + bird into T2 land drop, alt cast rider, tap all + bird, cast evo targeting rider, have one of our 8 or 9 cmc beaters ready to go.
End raze represents a hypothetical turn 4 consistent win assuming the steps above, ghalta is a fun because it turns a bricky hand into a good one, titan is grabbable off of rider from the get go but is actually our only 9 cmc and therefore semi-valuable to us because its a part of a supplemental pod line that grabs us kozilek who is otherwise unreachable off of rider, though is reachable off of an evo targeting any of our 8 drops.
Cycling cards feel less dead and help us chug along, which makes bristleback and wurm feel a lot better, tusker pulls double duty in this deck because not only is it a fantastic cycler but if we need to we can cast it and its cmc matches rider, making it an equally good evo target.
I kept this mono green and fairly simple because it helps rider function more consistently and its a pet card, but there's nothing stopping you from dropping a griselbrand, maybe grabbing some unearth's, and taking this into golgari, at that point you'd probably want grisly salvage, satyr wayfinder, stuff like that, blue has some good options too with things like torrential gearhulk, neoform, but I leave that as an exercise to the reader, it's not what I'm interested in playing.
Riftsweeper is a fun card with an obvious purpose, get evo back for us to use again, as well as letting us grab anything valuable we may have had to exile for rider, it can also just generally help us with exile which is more problematic for us than regular death, as we run repopulate and kozilek to give us our evo targets back otherwise.
Shaman is here to make brick hands not do that, bird enables the nut draw/play of firing off evo a turn early, also performs double duty as targetable body just for evo or pod to grab us a shaman if the hand is really that dead.
Terastodon, primus, and archetype are all just situational toolbox cards, lots of removal, a little removal and resiliency, and field protection respectively.
