It plays very nicely with Vial Smasher, Gleeful Grenadier and Rakish Crew for nigh-endless ping effects, so there could be a sneaky Rakdos deck in there somewhere
Maybe the deck already has a Shadowspear in it and you need something that's not that
Gifting either a Tapped Fish or a Food is essentially giving an opponent life in order to cast an undercosted spell (undercosted for the environment )
What I like about Imoti, Celebrant of Bounty is that it opens up weird cascade effects with giant stupid cards like Terastodon, Hullbreaker Horror, and Soul of the Harvest
Youre in good colors to benefit from support pieces like Cyberdrive Awakener (for the mass animation ETB), Cid, Freeflier Pilot, and Sram, Senior Edificer, too
