Obviously this is a very well-designed deck. Thanks, Wizards! I first played against a white-red competitive deck in Just for Fun, and that was no fun (opponent blocked for life!). But then I played two casual players and I had a blast.
Here is the deck ($7 from the bots for everything!!!)
And here is my third game, in which this deck just went wild. Slate of Ancestry gives me a new hand.
Wellwisher lets me gain one life for each elf I control.
Elvish Promenade gives me an elf token for each elf on the battlefield (sweet!).
25 tokens.
It was gg already, and I only attacked with the tokens. That was enough.
