Second batch of screen shots:
The sampling deck is great in Solitaire. Elves are all about overwhelming the opponent with little critters. Here is the first of two batches. I will annotate these screen shots as best I can.
Blanchwood Armor gives Quirion Ranger +1/+1 for each Forest I control... wow, that can be a big hit in a mono-green deck.
Rancor is also great, of course. Many of these elves were great in a specific set, a specific block, a specific limited environment. None of these four stick out as "wow, got to keep this one for the next round." When we look at the competitive Elf decks, the majority of those elves are one-drops. If an elf costs more than one mana, it has to be really, really special.
Here I show Primitive Etchings netting me an extra card. If you reveal a creature, you draw a card. The other enchantment that has a similar effect, and the same casting cost, is Rowen. With Rowen, if you reveal a basic land, you draw a card. I love learning about new Legacy cards.... there are so many interesting ones. These two enchantments deserve a brief deck building experiment.
Ivy Seer is a great casual Elf. It would be even better if it cost less than three mana. At three mana, its a fun card. If you drop it while you still have a hand full of green cards, it can boost one of your creatures a lot.
Caller of the Claw has a cool effect, and it fits better into a graveyard strategy or right after some of your elves have been removed. This is a defensive strategy.
Quirin Trailblazer is great to get more Forests on the board.
Steely Resolve gives all your elves Shroud. This ability is good only in some circumstances. Hexproof would be better because then you can enchant your elves. With Shroud, no one, not even you, can enchant that elf.
Burgeoning is really cool in the early game if you have a bunch of lands in your hand. A cool casual trick, to be sure.
