A couple weeks ago Andrew Boswell won the Standard Open in Baltimore with his trusty Abzan Aggro deck with Warden of the First Tree. He's been on Warden since it was printed, though most people have eschewed the card, or only adopted one copy for their Abzan decks, Boswell continues to jam four.

MTGO player "Fastfake" won the Dragons of Tarkir Constructed Championship with a very similar list. While he's not on the full four Wardens, three is a deviation from the norm in winning lists.

Warden is a card that I've been saying will see a modest price bump when Fleecemain Lion rotates, and and if Warden can see play now, I see no reason it won't see even more play when Rotation happens. For a mythic rare, Warden is really cheap right now, and I like it as a spec, or minimally as a trade target.
