Possibly the most vital card here is Steward of the Harvest, which lets you turn all your creatures into up to three lands that you can exile from your graveyard
A similar card is Destructive Revelry , costing RG to destroy target artifact or enchantment and dealing 2 damage to its controller
Reidane, God of the Worthy / Valkmira, Protectors Shield Speaking of snow, Reidane, God of the Worthy is pretty nice as one of the few pieces of snow hate
The mechanic as a whole seems quite hard to deal with since its on an emblem and its operating in a zone thats difficult to interact with, just like with dungeons
Collectors have a fair chance to crack this card by chance, and anyone who wants a guaranteed Ring can easily get it from either type of Bundle
If one of the lands in this cycle becomes a creature because of an effect other than its own ability, its last ability will still trigger whenever it attacks
