Its only one precon, but it does come with six different legendary creatures who could work as your commander depending on how you combine them (five of the cards have a special Partner mechanic called Character Select that lets you start with two of them in the command zone instead of just one)
Zimone, Paradox Sculptor Another version of everyone's favorite Simic math prodigy
So just imagine if youre playing Esix, Fractal Bloom, or some other big token maker, and dropping a bunch of creatures each turn
(Equipment, Auras you control, and counters are modifications.) Whenever this creature attacks, other modified creatures you control get +X/+X until end of turn, where X is this creature's power
Theyre almost mandatory support pieces, but theyre limited out of the command zone since you can only pair them with a Time Lord Doctor (sorry, Arcade Gannon)
You get extra land drops, slow opponents down, and turn sacrificed lands into card draw
