How about these for divine Strikers;
Hammer of Moradin; a dwarf cleric class that has access to stoneskin type protections, gains 3 faces during battle (that prevent flanking), that can fix enemies in place by melting stone/rock floors, can meld with stone to avoid attacks and that channels divine lightning into the enemy on successful hits with a hammer. Obviously some of these powers need to be available at higher levels.
Bringer of Divine Light.
An unarmoured, whitefire-rimed cleric that throws up to three light stones into the battle-area and can teleport between these locations, can deal divine touch attacks that channel powerful direct-damage, can mesmerise enemies, fixing them in place and can separate single monsters from the main battlefield by surrounding them with a damaging ring of divine white fire.
