Budget High Tide (four Copies Of One Rare)
This deck is a combo deck that can win on turn three. During the first two or three turns, just play islands. Then on turn three or four, or even later if you need to, play High Tide. Then, play tons of mass card-drawing spells in the form of Brainstorm, Frantic Search, Ideas Unbound and Meditate. To keep going without running out of mana, play untappers such as Cloud of Faeries, Snap, and Frantic Search. Any excess Faeries can be cycled instead of played. Finally, mill your opponent with Brain Freeze (you may need to play two Brain Freezes to win). Arcane Denial serves as an answer to any big problem your opponent might play, such as Lobotomy or Cranial Extraction. It also serves as a card-drawing card. If you can't find High Tide, use Impulse or Brainstorm to find it. I haven't made a sideboard for this deck, but I do have suggestions. Quash works well against Lobotomy and Cranial Extraction. Counterspell can be sideboarded against any deck that has a lot of huge threats. Propaganda would even work well against beatdown decks such as Sligh, Suicide Black, White Weenie, and Stompy. The rest is up to you. Have fun with the deck!
