While Your Favorite Character will never be the most powerful commander, if you just really want to build a themed deck around, well, your favorite character, this is an option now
Therefore, if you are considering combo, my recommendation is to either have a combo that slays everyone quickly or add a few combo cards to decks that already exist, and if possible, to have those combo cards not look shockingly out of place
Development, on the other hand, needs to care about how people play based on all the tiny measurements
Vilis, Broker of Blood Should you choose to accept it, your pact with Vilis, Broker of Blood involves paying life and mana to remove creatures by diminishing their power and toughness (yay for getting around indestructible)
In fact, if you want to sell them you'll have difficulty finding a vendor who will pay you more than what it costs to ship the cards
You can think about Lightning bolt, that can be used as a removal or a burn spell, depending on the situation
