In standard this is sadly too underwhelming. With Deathrattle activators rotating out it’s going to have a hard time doing anything, seeing how control hunter does not seem to be on the cusp of rising. In wild, you can do some more interesting things with this (since you can properly build a deck with synergistic cards for this) and as a Wild player, I’m interested enough to give this a go.

I needed something to make Immortal Prelate (even) more relevant. This seems to do it. I like it. (And yes, I like Prelate. That it CAN be silenced doesn’t always mean it will be.)

Hmmm, in that case running high-cost Choose One spells in conjunction with Stalladris is not even great. It seems rather slow and, as you say, underwhelming. Especially seeing as how it dies to a lot of things I doubt that it will make a huge impact the way it is. In Wild it is significantly more powerful seeing as Jade Druid can use this early to amp up the speed with which it summons big jades. In standard however, so far I’m not seeing how it will be used properly. Mecha’Thun is not at all interested in it, and Togwaggle is rotating out. Druid needs a new identity, and I don’t think this alone can facilitate that. We do, however, still have a number of cards that will be revealed, so this might change if impactful spells are printed. We’ll have to see.

It should be noted that every choice on choose one cards cost 0. This means that you get two 0-cost copies in your hand. This makes combinations with Auctioneer and Malygos particularly potent.
