So make white, (Alpha edition, if it matters) - and ... wasn't that a card in the most recent un-set? Anyhow, hexproof or discard to double-hexproof.

White can sure throw around protection. Frankly, I think I could just colourshift that directly to white.

Well, let's alphirise-it too. (That is; prot-black instead of hexproof; and not clarifying that the effect doens't end at eot)

"Failing to say UEOT" is not an Alpha thing, that's a very specific Portal typo

No; I mean - this deliberately doesn't end at end of turn. Like thoughtlace, magical hack, etc.

Ah! Then your Alpha word template is too modernized. Here' let me help with that.

"You may discard this card from your hand at any time; it can not be regenerated. Doing so provides protection from black ability to any ONE creature. This ability does not end at end of turn, but instead lasts until the game is over. Cost to cast, tap, maintain, or use a special ability of target card remains entirely unchanged. Mark the changed creature with tokens."
