Of course, the potential of Silvergill Adept is somewhat limited by the fact that you need to play it in a Merfolk deck to cast it for two mana, and Naban isn't a Merfolk, but as the only straightforward "draw a card" Wizard in Standard, it still might be worth the effort if we can find a build to support the mixed tribal synergies
Then if it has ten or more point counters on it, remove them all and that player loses the game
Changelings are interesting because treefolk are usually expensive, so cards like Masked Vandal and Chameleon Colossus lower the curve and add versatility
Commander falls a bit in between these types, as it can be played both casually and competitively, with the former often being called EDH (Elder Dragon Highlander) and the latter cEDH
Controlling a player doesn't allow you to look at that player's sideboard
