looking for creatures in 5 color EDH that have great value when they die example being Academy Rector

Solemn Simulacrum should be in almost every edh deck ever.

Also:
Yavimaya Elder
Wurmcoil Engine
Sakura-Tribe Elder
The Kamigawa Dragons
Ashen Rider

I'm guessing this is for a Child of Alara build?

Here are some from a quick advanced search of the card database:

Ashen Rider
Brindle Shoat
Doomed Traveler
Gang of Devils
Loyal Cathar
Maalfeld Twins
Mausoleum Guard
Moldgraf Monstrosity
Polluted Dead
Runewing
Soulcage Fiend
Undead Executioner
Underworld Cerberus
Vastwood Hydra
Voice of Resurgence
Worldspine Wurm
Xathrid Necromancer

If you are going to let your creatures die, why not include some creatures that benefit you whenever a creature dies:
Blood Artist
Falkenrath Noble
Harvester of Souls
Havengul Vampire
Lumberknot
Ogre Slumlord
Rage Thrower
Requiem Angel
Unruly Mob
