Part of what makes the combo so strong is that Exarch and Pestermite have Flash and can tap down an opponents Land at the end of their third turn
The Vampire creature either functions as a Blind Obedience or, if your opponents really need to have their early mana rocks enter untapped, the Conqueror threatens to make a ton of tokens
That said, this is a powerful card and I think it will be played
Connive makes sense from a flavor perspective, even if its not the freshest mechanic, but the bigger issue here is the overlapping strategies
This involves jumping through a few hoops, but they arent particularly difficult onesjust protect the card if they attempt to destroy it more than once, then clear their field on your turn to go for the game
Give your collection the archival-level care it deserves
