And finally Frodo & Sam are the best choice if you want to focus on the Food + Lifegain aspect of the deck, as Sam provides a ton of lifegain for the deck while Frodo uses that lifegain to generate a lot of incremental value
Banding is two abilities - one that works while it's attacking, and one that works while it's blocking
Harmonize [c]Harmonize[/c] is one of the simpler cards on this list
