Pretty typical Ezuri elf tribal deck. Not intended for 1 on 1 or a competitive but has been a very aggressive deck none the less.

Cards on the chopping block
Defiant Elf - More nostalgia than anything else. Trample hasn't been super relevant.
Llanowar Elite - same.
Bramblewood Paragon - Seems like an elf lord at first glance, hardly gives out counters+trample to my other elves.
Gilt-Leaf Seer - Card I've always thought was interesting, card filter on an elf. Never used the ability yet.
Wirewood Herald - Already have Elvish Harbinger, not sure intentionally killing this creature will be worth it. I'm also under the assumption that when the board gets blown up, this won't really help finding me an elf lord at that point. Worth testing some more though.
Timberwatch Elf - Nostalgia. Can make something huge, went well with 1cmc elves with trample. Most lists I've seen don't run him and that's understandable. Haven't gotten a chance to play with him since games with this deck have been ending too quickly.
Immaculate Magistrate - Same.
Copperhorn Scout - Powerful in theory, not sure if it's what I want though. Most lists don't run him. I guess with a few elves that produce mana and Ezuri out, I can hold up a blocking overrun or regeneration wall so at face value that seems good.
Essence Warden - 1 drop. Gains a bunch of life. Not sure It's what I'm looking for but I'll try her out some more.
Yeva, Nature's Herald - last minute throw in because an elf, and why not. Will she be amazing? Probably not, but along all the other subpar options I'm running for now, she doesn't stand out as terrible.

Cards I will be replacing.
Crystal Vein --> Nykthos, shrine to Nyx
Lifeblood Hydra --> Genesis Wave. seems too slow in the testing I've done. Would much rather have G Wave.
Collective Unconscious --> Harmonize. I feel CU is a win more card and requires me to extend to justify paying 6 mana to draw enough cards, while it scales up, I feel like the fact I can't use it ALL the time will make it a dead to situational card. Harmonize has always done what I needed it to.
Song of the Dryads --> Elvish Champion. The deck is already very aggressive and removal light. Mono green already being the worst at removal, I feel like I'd rather just push damage than run this, beast within, and or dessert twister.
Gilt-Leaf Archdruid --> Caged Sun. I don't have enough druids to really get the draw effect, or the second land stealing ability for that matter.
Masked Admirers --> ? I've seen some lists run them, I'm not convinced paying 4 to draw a card is good enough, and paying 2 when casting a creature spell to get them back AND pay another 4 to draw another card, not impressed with it.

Cards I want to Add
Coat of Arms? - I feel like it's just the default go to tribal card and I'm not really sure I want to shove it in everything tribal.
Artifact destroying elves.
