With the morph ability seemingly tacked on hastily, the real question is whether there will be a card, possibly in Temur, possibly just somewhere in the set that reduces Morph costs, either to play them facedown or to flip them. If you could play this guy for 1 mana facedown then flip him to net two mana, that could be very cool. He flips up for 2 and gives you 3 plus he can tap when he flips up if he was in play facedown at the start of the turn, so there are potential shenanigans here. Still, he's mostly likely just a solid mana fixer. He has fewer toughness and much less hexproof than Sylvan Caryatid which means he is likely extra copies of Caryatid if needed until roptation unless there is some significance to his morph ability. Turning colorless mana into colored mana in a configuration you can't designate one time isn't stellar, but it may be the ability we'll need.
In a vacuum, this card is tad underwhelming so far, so we'll have to see what the rest of the set gives us.
