From the wording it should shuffle in spells your opponent plays as well, which can invite a lot of counter play. A control deck can play this alongside a board clear to prevent counter play. Could see play alongside Brawl or Hagatha's Scheme .

I'm thinking it should and probably will. It'll be fun to watch people who don't realize that, use a direct removal spell on it and then later you cast said spell on one of their own.

oh baby. Stowaway suddenly got a whole lot better. Play this + Togwaggle's treasure, stowaway next turn gets you another togwaggles treasure guaranteed.

An elephant never forgets.

This card would see play in decks with tons of spells, mage, priest, and paladin are the strongest with him. priest and paladin could even copy or duplicate the elekk for more cards in deck. can help classes stay ahead in the fatigue game or generate more cards, may experiment adding him to cube priest....

shaman too

You forget about Rogue treasures dude.  This card is scary good in rogue since rogue can also pull the shuffled spells out of their deck

Elekk card without mentioning rogue... Shadows, stowaway followed by eviscerate, sap. Even sprint... Also add in galak or lackies.
