While theres a lot of synergy here, the cards are mostly strong independently, and the deck is designed to play a fair, interactive game that just happens to be able to gain infinite life with Urza and the Thopter Foundry / Sword of the Meek Combo, but mostly Urza, Oko, and Emry are all amazing standalone cards that require fairly different answers
And while this is a good effect, a lot of things need to happen for it to work
This card is so good, I didnt even need to point out that a 3/3 for three mana and haste is already solid on its own
#7: Crystal Chimes Esper has a bunch of ways to bring back artifacts and enchantments from the graveyard, but many of the best ones bring them directly onto the battlefield, which doesnt trigger Alela
