I recently bought a "deck builders" kit that included, among other things, a Dark Ascension booster with Scorned Villager (a double-sided card) in it. It did not include a checklist card for me to use.
If I wanted to use this in tournament play, I realize I'd have to buy sleeves or acquire more checklists, but for now I'm mostly playing casual games. Are there any alternatives that would be "generally accepted" among M:TG players for using these cards? e.g. marking up the face of some land card to indicate that it's really my Scorned Villager?
Alternatively, is there a good place to get checklist cards that won't also result in getting more double-sided cards to go along with them?
