I feel like these designs are telling.
"Ancestral" is just good and it would be run in most blue decks. I suspect it's better than Ponder in almost everything, and better than Brainstorm in decks that specific reasons to want to discard. I would love to play with this card but I doubt it makes the format more balanced.
"Erase" is just a strictly better Fragmentize. Since Fragmentize is already very good, this would obviously see play. Note that "uncounterable" is the least important in artifact hate, because a Workshop deck isn't going to misstep this. Even if it didn't have the "uncounterable" clause, this would be the best Disenchant effect ever printed. I don't know that it would hurt the format, but I'm not sure whether we want them to be that good.
but "Ritual" and "Growth" are just unplayable affects. No deck would be improved by these cards, and I'm having difficulty imagining the situation in which I would want to have counters for them. Without deviating too much from the design discussion, I really feel like if you're looking at a card like "add BB, uncounterable" as better than "add BBB", then you are dramatically overestimating how bad it is to get your cards countered, and you're probably not running cards that you should be running, out of fear that someone might answer them. Getting your cards countered isn't nearly as bad as not running any cards that are worth being countered.
"Lightning", though, is the most interesting card, which I could see being relevant in maybe a Delver metagame? It has close parallels with Sudden Shock which costs one more but is also much better against Arcbound Ravager and Monastery Mentor and sees almost no play anymore. Still, I think this card would have no downside to the format, and have some small positive impact.
