That card is incredible.
I assume it goes back into your hand?
That card allows for Reno Quest Mage to operate:
1) Sorcerer's Apprentice in your hand.
2) Simulacrum.
3) On another turn, Sorcerer's Apprentice x2 gets played. (4 mana)
4) Molten Reflection for 2 gives you a third. (6 mana)
5) Echo of Medivh for 1 gives you 3 more in your hand (lol). (7 mana).
6) Sorcerer's Apprentice. (9 mana).
7) Time Warp for 1. (10 mana)
Alternatively, you could use Emperor Thaurissan and do:
1) Sorcerer's Apprentice in your hand.
2) Simulacrum.
3) Thaurissan your Sorcerer's Apprentice x2.
4) On another turn, Sorcerer's Apprentice x2. (2 mana).
5) Echo of Medivh. (4 mana).
6) Sorcerer's Apprentice x2. (8 mana).
7) Time Warp for 1. (9 mana)
That card is going to make some dreams come true. Reno Quest OTK Mage is going to become huge in Wild.
Previously you needed a much more greedy Thaurissan to pull this off, and it was pretty prohibitive in my experience.
