All these different Talisman 'revoking costs' irritate me. I would consider standardizing one way or another.

Here's a quick sketch:

> "Revoke" (Enchanted permanent's controller may pay at any time to have you draw a card and sacrifice this Aura.)

Draw's there to make it more questionable whether the ability is actually a drawback or not.

Finally getting around to replying to this. I was strongly considering adding the draw effect earlier, but I was concerned about the ramifications of giving White more sources of card draw. I plan on drafting up some common-only archetype decks soon - if Talismans prove weak or boring, its definitely one of the first things I'll add.

Adding the draw will also lend more of an argument to making it a keyworded mechanic, too. I was pretty hesitant to keyword an all-drawback mechanic.

All colors get cantrips/cycling so getting "draw" out of the mechanic is not an issue. Capashen Standard is perfectly fine for example. Arguably Angelic Gift as well. Plus, you know, has dappled with the enchantress theme before so even if it was pushing so color pie boundary...

I would definitely try out the keyword. Unless a mechanic is named, it's likely that players won't realize it's a mechanic (or a theme). Like that aforementioned Capashen Standard and Brass Secretary were meant to be a "cycling from play" mechanic, but very few of the players got it since it specifically didn't have a name. To levitate this issue, if you didn't want to make it a parameterized keyword, you could alternatively make it a pseudokeyword.
