Almost any card that lets you untap permanents can be considered good, even if it has limitations like this one with the snow type
The only exception would be if multiple effects that altered a Creature type were in play at the same time, particularly if they're using replacement effects (i.e., changing a Creature's type from one to another)
If you create showcases or binders and set them to public mode, people can send a "like" reaction as if they are a Facebook post
Pros: One-sided board wipe on a creature Decent stats Cons: Slow Requires a certain amount of lands to be effective How you can get it: Journey Into Nyx 6
This prevents the algorithm from recognizing the same card more than once
For instance, the new blue Shrine from Magic 's new Kamigawa: Neon Dynasty set only mills one target player and the green Shrine only cares about putting +1/+1 counters on other Shrines its controller has, not working towards any game plan in particular
