In addition to featuring new Paldean species, Scarlet & Violet Paldea Evolved also features species from previous regions
The general idea of an elf deck is to jam as many elves into play as possible, using all those cards that tap for multiple mana to cast many, many spells a turn alongside effects like Glimpse of Nature and Champions of the Perfect to draw a bunch of extra cards
Ive spent a couple of hours going through all sorts of creatures and token generators to see what I could do with this Commander
As long as you have about two or three of them, Id always play this
In fair decks, you get cards and an ally, except for Cut a Deal, which seems the most sketch
If you are not familiar with the cards and not good at evaluating things on the fly, I highly recommend looking up the card image gallery for the set you are drafting in advance so you can have some baseline evaluations to go from (or you at least have read the cards before)
