Well his being a Leader tempers Legionnaire Strategy quite a bit since if you reveal OM 1 on him, you're not getting the bonding that turn, and if you don't reveal OM 1 on him, you're not getting bonding until you reveal an OM on him.
Something to keep in mind with the whole Leader/Lego debate ... though I think Legionnaire might also be less confusing on him for this reason.
Number after the name for Magnetic Throw works fine for me.
I prefer him a bit weaker than Mags, though.
