One thing this set has in common with Tales of Middle Earth is an eye for creative card effects that bring home the theme While there are lots of great thematic cards to enjoy, because this set is part of the standard format, you have to consider how the various effects will integrate with other releases for the game
It could be an Emrakul, the Aeons Torn, or perhaps that Placid Rottentail will hop right back out
Sideboards that probably should have had this card due to its ability to dominate a board decided to take a pass
Incubator tokens are predefined, like food or treasure, meaning that they have an ability baked into them in this case, all incubator tokens have the ability 2: Transform this artifact. The flip side of Incubator tokens are 0/0 Phyrexian artifact creatures, so this mechanic is effectively a way to give you token creatures of varying sizes for an extra 2 mana that you can pay later
Hades is a more straightforward payoff that removes a character from play by putting it into their controllers inkwell, and then sticks around after to quest and challenge
This is the kind of card, for example, that led to Ambassador Oak where one card represents two creatures rather than one
