Is Thoughtcast with multiple creature type requirements that good? Feels like a Ux Fish kind of card, seems unlikely that it should be strong enough to get restricted
The current restricted list has a number of Xerox-ey cards, but I don't think we've ever had a restriction that really hit Fish-type decks more than other archetypes.
Fishlike decks tend to be pretty reactive and metagamey, which makes it hard for them to become really dominant
Very interesting. I think the pitch counters in both HollowVine and Dredge load more of the value of your deck into your opening hand, and having strong early hate-bear options mirrors this quite a bit.
It feels to me like Pitch Dredge showed that there was room in the Dredge archetype to load in almost any package you wanted. That point was driven home by Zias' Shops/Dredge hybrids, and now we're looking at massive hybridization of the Bazaar-as-creature-engine concept. Admittedly, in HollowVine decks the Bazaar doesn't serve quite so squarely as a graveyard engine in particular, but it feels like a close cousin to me.
My personal preference is always to maximize consistency if your deck has sufficient power level. I would be interested in seeing a version of the HollowX archetype with artifact-based lock pieces, because the mana for that can be much more consistent (one mana source being sufficient for almost all lock pieces). Granted this would weaken Once Upon a Time quite a bit, but perhaps it would be worthwhile.
