Even better is:

  31 Ancestral Recall
  25 Black Lotus
  3 Timetwister
  1 Braingeyser

You don't need 2x of any one thing to get started, you only need 1 Lotus and 1 Timetwister or Ancestral Recall.

If anything gets countered, you are very, very likely to be able to keep going and win the same turn.

Timetwister lets you recycle, so you can generate infinite mana.

Braingeyser kills the opponent, and doubles as card draw itself, in the unlikely event that you stall out.

You also don't lose to a turn 1 Lightning Bolt, like you do with Channel.

A mulligan to two still has a fairly high likelihood of winning on the first turn.
