Theres a best Vampire Commander here for every kind of player

Planar Nexus: Pretty absurd, given its ability to turn on Tron alongside just one of the Tron lands like Urza's Mine

There is a particularly great tie-in story to King in Black from Planet of the Symbiotes #2 by Marc Bernardin and Kyle Hotz where American Kaiju (Godzilla with an American flag emblazoned on his chest - look it up if you don't believe me) fights off hordes of Grendel dragons

TCGplayer also has a mobile app that makes uploading a collection easier, though its probably not the best for inventorying large amounts of bulk, since you need to individually scan cards
