The recent improvement in the builds of the Abzan Midrange Standard deck is the inclusion of a card that can be beneficial for the deck in the late game. The card is Den Protector and has been in the Abzan list piloted by seasoned pros in the Grand Prix last weekend. Its uses are for returning utility cards like Abzan Charm and relevant creatures/planeswalkers in the late game like Siege Rhino and Elspeth.

Here is what I think the decklist would look like:

Creatures
4 Courser of Kruphix
3 Den Protector
4 Siege Rhino
1 Tasigur, the Golden Fang

Spells
4 Hero’s Downfall
3 Thoughtseize
4 Abzan Charm
1 End Hostilities
2 Ultimate Price
3 Bile Blight
1 Murderous Cut
1 Utter End

Planeswalkers
2 Elspeth, Sun’s Champion
1 Ugin, the Spirit Dragon

Lands
4 Windswept Heath
4 Temple of Silence
4 Temple of Malady
4 Sandsteppe Citadel
3 Llanowar Wastes
2 Plains
2 Caves of Koilos
2 Forest
1 Urborg, Tomb of Yawgmoth
