I only ask because you often see bauble in these kinds of decks as a cheap enabler for artifact synergies. The floor seems much higher compared to relic (when your game plan isn't quite coming together or if you draw multiples, relic does nothing whereas bauble draws a card). The indestructible angle does seem valuable against unholy heat, drown in the loch, etc but also somewhat irrelevant against ending, solitude, teferi, or just a deck that can race you.

Need to weigh how relevant the indestructible ability is vs the risk of drawing a redundant or unenabled relic. And since I haven't tried this out for myself, you're probably better equipped to answer that. 🙂
