I had Counterfeit this Weekend Ranked all the time and before that for a while in Ethereal Diamond and Mythic. It can steal Necroscepter or Enduring Shield. Moonlight Charm is a nice one either but it is not too often.
But too often Counterfeit hangs out idle. There were cases when I had 2-3 cards and one of them was Counterfeit while my opponent has no relic. Paying 3 mana for drawing card isn't what I dream about.
Also, my Deception deck has a good chance to beat Death / Nature without Counterfeit and I too often lose to War with Counterfeit. So what is the sense?
Probably, I won't have it next weekend.
Having subpar creatures is even sadder. They don't meet relics too often and you lose an opportunity to use better cards.
Your idea about having a blessed creature instead of a relic-remover looks interesting. My current Deception deck has one Ludia's Dedicant. Probably, having another one instead of Counterfeit may be an answer.
