Yes, as it should be, as it should be! Let's go for Luke!!!
If we're talking about the game, a blocker that sacrifices itself – maybe, but it feels a bit risky to play with something like that.

with a 50% chance, it saves the selected player from an attack.

I don't really like this. It's quite weak. Either give it a full-fledged defensive ability, maybe with some kind of 50% additional bonus, or just let it function without a defensive ability.
