I think people are sleeping on this as a multi-function mage card. Discover a spell is good, it's on par with Vulpera in that regard which again is an ok card for mage. However this is also an elemental AND has spell damage. Elemental Allies suddenly looks a lot more viable, especially if Mana Cyclone is playable again with all these 1 mana cards.
Quick look at good elementals we can play in the deck:
Mana Cyclone, Zephrys, Siamat. Ok ones we can play: Animated Avalanche, Violet Spellwing, Chenvaala, Mana Giant, Arcane Amplifier, Water Elemental, Al'ar.
AND it's an activator on curve for Sorc. Subsitute, and all the other new spell damage effects.
5/5 will be in every elemental deck, and a good deal of spell damage decks
