I ended up cutting a lot of the anthem elves because I think ultimately my plan is more to use a large number of elves to generate mana from means of things like Gaea's Cradle / Earthcraft / Priest of Titania and use that mana to pump my elves up via Numa, Joraga Chieftain. Its a touch different but I guess we will see if it works.
Overall, it felt like I had to kind of full commit to elves so my overall interactions aren't much. I primarily stick to elves and things to make mana or draw cards. Its a more proactive approach for sure. When I started this list I started with something like 70+ creatures in the list and had to HEAVILY trim. Its entirely possible I overlooked something super obvious outside of the elves (like grave hate which I have none of).
