Edit1: confirmed by BAgate; Edit2: changed thread title to match new report guidelines

Also:

1) If Thousand-Year Elixir comes into play after a creature does, that creature is not affected.

2) If Thousand-Year Elixir is tapped when a creature comes into play that creature is not affected.

And it was improperly removed if you had two copies of Thousand-Year Elixir, one left play, and the other wasn't somehow an enchantment. Fixed in 44c140e.

For the record, doesn't effect non C cards.

But strange bug, the haste is granted to creatures before it enters the battlefield. Ex. I cast a Balduvian Conjurer, then Thousand-Year Elixir, and when I am asked for fast effects for casting the elixir the Balduvian Conjurer is available.

Fixed it working on the stack in 79b3b5f.
