I think it's interesting that people want to "play competitive" magic but dont' want to put time/effort/$$$ into it
Once the game setup is done the players decide who goes first (can be by flipping a coin, dice, rock paper scissors or basically any way they want)
Creatures with the Prepare keyword show up in these dual-bottomed card frames (like Adventures and Omens), on the left you'll see any relevant stats for the creatures, and on the right in their own little box, with its own mana cost, you'll see the spell they need to "prepare" to cast
You can still counter the activated ability of a Clue itself, but thats completely separate
Wild horses in an endless field
So, overall, both in terms of the card itself and its in-game utility, you can see why Mufasa is so sought after
