It's always super unfortunate when stuff like this happens; I wonder if something like Elvish Warmaster could be a decent shout? Yes, it's a two drop, and it seems like you're looking for something more akin to the top end of the Selesnya tokens deck, but the card seems like it could be powerful in your environment. It's a great mana sink, has good synergy and is roughly $1. As an added bonus, the art fits the vibe of your cube. Love the Podcast.
