It works rather unintuitively, but I think it's also a lot of fun to play, as well as quite strong, so I will try to illuminate our thoughts and choices that went into this deck
If your strategy already involves swinging out with a lot of creatures to get around blockers, this card can help protect some of the creatures you know are likely to die in the attack
Dropping this monster at seven mana results in any instant or sorcery of your choosing to hit the stack, an exciting prospect for a card I know makes the cut in Standard
This two-mana enchantment transforms every draw step into a powerful filtering effect that improves hand quality while providing optional card advantage (similar in some ways, to the best Pokmon deck schemes that prioritize many of the same goals)
There are plenty of great reprints, like Craterhoof Behemoth, Phyrexian Tower, and Rhystic Study
