And..... You mulligan until you get your Treasure Hunt? What if it get countered?
Or worst, Dissipate...... Still a nice combo, but you should at least find one alternate win condition
Actually, Parallel Thoughts works as well for getting to the Treasure Hunt. But yeah, I'd like another good way to get to things to start the combo. But yeah, it's a balsa wood table of a deck; there's a lot of ways to make it kindling. Still amusing, though.
Why not make it for modern or vintage? The deck would be much better in a 4 cards format. I'm not sure it belong in EDH, more than that, this type of turn 3 win combo will not be welcome in most playgroup.
The way i see it, you'll play the deck once and win. Then two option, your friend will not want to play against this deck anymore OR will get an answer to you deck everytime since your combo and win condition will always be the same.
Lots of way to counter the combo including counterspells, boardwipes, enchantment removal.
