Obi-Wan Kenobi, Only Hope

{u}, Mind trick: Whenever an opponent declares an attack with a creature, you may reassign targets for attacking creature. (New targets may assign blockers)

Only hope: Whenever you block with a creature you may tap up to two of your target creatures, you gain life equal to their toughness. (Activate only as a sorcery)

When this creature dies, become one with the force: You may use abilities that aren't mana abilities from this card even after death
