Since official tournaments all require opaque sleeves anyway (and the vast majority of people I've played against at various locations use them even when not in an official tournament) I think a cool addition to the OP Kits would be errated versions of Bait n' Switch, Library Access and Drummernaut that people could use to replace thos ecards in their decks - just in the interest of lessening confusion - no everyone is always up on the errata.

You could even have the opposite side be a chain tracker since FFG seems to really want to flood the playerbase with those
