In other words, the very first card to use typal coupling did so because of flavor
Some examples might be: Kindred Enchantment - Eldrazi Kindred Sorcery - Goblin Kindred Instant - Faerie Kindred Artifact - Lhurgoyf These used to be known as Tribal 'Card Type', and are now known as Kindred 'Card Type' as of Modern Horizons 3
Let's say that you build a deck where your only creatures are one copy of Street Wraith and two copies of Emrakul, the Aeons Torn (just in case you happen to draw one of them)
If youve played Aura-based decks in the past, you know how much of a balancing act they can be to play
The melded permanent will behave like a single permanent, but if Urza, Planeswalker dies (spoiler alert, lmao), gets exiled or just leaves the battlefield, the meld breaks and it is back to the two cards
There have been some really cool mono-red commanders to choose from over the years, but Torbran brings damage-based red strategy right back to the front of the class
