What commanders have the most branching decision trees or variable mechanics that make each game feel different?

Examples of what I mean:

•Clone/Theft Commanders: I can have a different gameplan everygame depending of my opponents decks.

•Partner commanders: I can have different playstiles and colors depending of which partners I choose.

•Choose a Backrgound commanders: Literally swaping half your command zone, kinda the same as Partners.

•Maybe even Politics commanders: Every game is gonna be different based on who would side with me and who wouldn’t.

•An specific example of what I’m looking for would be something like [[Sefris of the Hidden Ways]] , I can venture into different Dungeons depending on the boardstate and my cards in hand, is not just “I’ll play my cards to follow my gameplan”, but my gameplan is constantly changing too.

What else fit this that you think would be fun?
