uncommon. From a design perspective, the difference between Wall of Blossoms
and Carven Caryatid lies in the critical question: "How much is drawing a card off of a creature coming into play worth?" Wall of Blossoms was only two mana, and easily splashable, and as a result R&D generally feels that the card was a bit too good because players were more likely to use it primarily for the card, and only secondarily for the wall. With Carven Caryatid the cost was upped by one and an extra colored mana was added, but in return the wall was given enough power to punish attacking weenies, significantly increasing the card's defensive potency and making the extra card a bit more of a secondary feature.
