I chose the long and painful
High Tide approach with decking as the only win condition. Kill was usually a huge
Brain Freeze followed by an
Ancestral Recall, or just a gigantic
Blue Sun's Zenith.
Since nothing else matters, stall and play out islands until the last possible moment. Since every card is instant, you can go off and win at any phase. Try to wait until you have 8 cards in hand and 4 island if you go off on your own turn.
Island x20
High Tide x4
Turnabout x4 (Mana combo)
Frantic Search x4
Snap x1
Ancestral Recall x1
Accumulated Knowledge x4
Meditate x4
Peer Through Depths x4 (Card draw / Tutor)
Thought Scour x3
Mystical Teachings x4
Cunning Wish x4
Blue Sun's Zenith x1
Brain Freeze x1 (Win conditions)
Pact of Negation x1
I need to do some bug hunting here. I frequently would find multiple copies of
Brain Freeze or
Blue Sun's Zenith in my deck while tutoring and there should only be one of each. Something was duping cards for me. Oh well, the deck works like a charm if you don't mind spending a huge amount of time on the combo each game xD
